Hi all,

As per title, want to ask, izzit ok to use different tyre profile for front and rear? I know we see this alot on supercar and superstreets car, but for daily drive car does it affect anything?

Here the purpose size, front: 205 40 17 rear: 205 45 17, and ofcoz will using same tyre thread

Appreciate your inputs.

I been using 50x15 for front and 55x15 for rear around 8 years and I can't see got problem .

Ur car rear wheel drive or front?

If the circumferance different percentage is too much will upset abs and vsc function.

I wantto know too.. Coz my stock tyres hard to find 175/65 R15

The question I put to you is, if your car came with same size tires for front and rear, what is the reason you are looking to change this setup? Factory setup was such for a reason. It's not for show.

More likely to setting with different tyre width than circumference...kind of odd that you want to do something like this.

Why do you want to use such different profile only? What is your car? Usually those with different/staggered tire sizes are RWD or AWD cars (but with more power to the rear wheels) so they use wider rear tires to help maintain more stable handling and control the power/traction to the road. For FWD, it's not recommended to use such staggered setup coz it will make the handling even more understeer. Your setup is odd and makes not much purpose as the tire widths are still about the same only the front is thinner by 1 cm or total diameter is actually smaller by 2 cm at the front. If you can use 205/45 in the front as well then better to do so.

I'm actually using a staggered setup with front 225/50/17 on 7.5jj and rear 245/45/17 on 8.5jj. Note that the total diameter between front & rear are almost the same with only about 4 mm difference, not as much as yours. Does it affect anything? Yes, my car is a RWD and it makes my high speed handling/cornering more stable, more predictable, and easier to control over the limit, especially since my car has no TRC/VSC.

Actually im not using stock size, just want to know if the difference profile Does effect the ride and handling quality

Thats what im concern, i need the input before put on. Currently wearing 205 40 17 on my 9jj rims, my car is persona and im stancers, i know stancers will looks wrong and unbrain by some drivers, but respect the culture.

So im here not to play blame game, lets put it informative as much.

The car is front rear drive, as im concern im using this setup for daily drive. So the inputs from perfomance mania are needed for my knowledge

If you really value proper performance input then you would not be a 'stancer' in the first place and should replace that 9jj rims with no more than 7.5jj rims as recommended for your tire size.

no disrespect to your culture. but the wrong rim size, weight and the fact that you are already stretching your tyre so much affects the ride way more than the the staggered size. so i guess since your car is already rather dangerous, there is no further harm going staggered.

Put a side perfomance, but what im asking is for daily drive, i do spare rim 7.5j rpo for spirit driving but it doesn't looks nice hahah, yes stancer and perfomance didnt blend together.

For size 205/45/17 and 205/40/17, the different is very small..
I thought like 205/45/17 front n 235/45/17 rear.. So if like urs size, i dont think u have a lot of problem.. Just u can rotate front n rear tyre that's all..

As you've agreed, performance and stance can't shake hands. Thus, forget performance.

I respect the culture, but only if your car is a show car or a weekend car, just cruising on highways or empty roads like Putrajaya.

If your car is a daily driven car, I totally have no respect for stance culture. Why? For starters, you guys are putting yourself at risk by driving on public roads with such setup. And when you put yourself at risk, you put others at risk as well.

1. Stance cars slows down so much at speed bumps, they become a nuisance to the traffic behind. Same goes for steep ramps.
2. Incorrect tire size for the rim width. It stretches your tire wall, which leaves little room for additional flexing. And that is dangerous.
3. I pity your passengers when you ferry them. Your stance look requires stiffen springs/suspension, with bump stops so that it doesn't bottom out. And on cars such as Persona or any lightweight cars, that makes your car jump up and down on our local roads, if you know the quality of our roads. Thus, your passengers would be nauseous after a long arduous journey.

Lets put it this way, which is what you want to hear. Different tire sizes for front and rear may not adversely affect the drive-ability of your ride, and it should pose no issue if you don't speed (typically, stancers don't speed but I've been proven wrong many times). As long as it can clear your fenders, slight different in size should be no problem. But don't quote me as I personally do not recommend it.

Im not to argue with your point either to say right or wrong.

thx for your concern.

The purpose of this is actually to made the fitment looks nice for rear inside fender.

Yes i cant rotate, in a year i change my tyre 2times because of camber.

Eh, if looks over function is the main thing here. Why is it any of a concern? Furthermore, not sure if you can notice any much difference visually with just a 5% difference over a 205mm width tire. But the price might grow quite a bit on you even if you can find the same brand same model tire in same width but 5% lower profile.

Furthermore, you mentioned supercar and some supercar has different width front and rear. So, it is normal to see different profiles front and rear. Some supercars even have different rim sizes front and rear.

So, if you have like 205/40 on the fronts and 235/35 on the rear. It might make sense because the circumference difference is not too big.

Well then why you asked for input from performance point of view? You're now contradicting yourself already. Forget about performance, honestly in my opinion, your setup or what you call 'stance culture' is not even road worthy in the first place, not to mention being a daily drive! I agree with what McFD2R stated below and my opinion will even go further than him! You ask for respect for 'stancers' but in fact 'stancers' themselves do not respect others as they endanger others by stretching tires to such extreme and running on such extreme camber. Then they also slow down so much even during minor road imperfections, making other people have to wait damn extra long for them to pass. Do you think you guys own the road or something so you can take your own sweet time on them?? Heck you don't even respect your cars by subjecting them like tamiya toys, ruining their fenders, tires, rims, suspensions, undercarriage etc2. So how do you expect others to respect such egoistic nuisance?? And all that for what, just to look 'good', or so people will say you're 'cool' or something? Sorry, you won't get any from me or any other with a sensible mind, and I don't even think such setup looks any remotely cool/nice/good in the first place, those cars look like broken cars already coz they're indeed already on messed up suspension! If you want respect, start by respecting others first and forget about 'stance' or whatever that is.

Well IMHO they should not be road legal in the first place, especially on highways!

Oftentimes, there is no reason. Just GAYA, MUTU, KEUNGGULAN.

Yes, I already know what is the TS intention hence my post just earlier.

We all know that, even TS. The car is all about show, but no go.

Well, the rule of thumb is, your tires aren't suppose to protrude from your fenders. But you know, this is Malaysia Boleh land ... JPJ or SPAD don't really strictly enforce this.

Unfortunately not just in Malaysia but this disease has spread in many other countries too without any control from the law enforcers!

Ok times to pencen! Brb!
Haha. Why so serious bro?

Yes bro, gaya muthu keungulan, nothing to do with racing and track day

Gaya? Macam mana ada gaya? The badge itself say something else!

haha just answer his question la. anway i think doesnt affect that much. but sports car usually use different width..but the diameter remains the same.

Pay attention to what I've said, your 'stance culture' endanger other people only for your 'gaya muthu keunggulan' nonsense, that's why I'm serious, got it!?

Well I've answered his question in the first page already.

u didnt mention your car..i assume your setup based on your own mod. i refer to oem setup for certain bmw model. just for example.

if prefer same profile but rear with wider thread

example

front 185/55/R16
rear 205/55/R16

for me don't mess up the odometer reading and your stock rim offset.

Ok noted, please pay more attention at kanjo trend in malysia now as their race at public road more!

He answer already and the same time back fire on me haha..

Your rear tire size increases the overall diameter from 24 inch to 24.9 inch. This will create a raised rear looking profile on the car. If you want it closer to stock, rear go for 205/50/16, in which the overall diameter of the rear tires would be 24.1 inch.

This is just for the sake of tire size discussion. My stand on stance cars for daily driven cars is still the same.

The stock was 195 60 15, the close diameter are 205 45 17, but now im using 205 40 17, if u do 140 actually speed only 120

so you are using persona...

stock rim is 6Jx15 ET40 if your tire is 195/60R15 .

for 17"

205/50R17 x 6 ET45 = +0.8%
215/40R17 x 7.5 ET40 = +0.4%
225/45R17 x 8 ET35 = +0.4%
245/35R18 x 8.5 ET25 = -0.5%

this is the closest setting to OEM.

Well that makes it even more dangerous and I don't pay attention to useless nuisance.

Yup, my setup is based on my own mod in conjunction with some bars upgrades as well which I'm quite content already as an overall package.

satria neo cps use narrower front track compared to rear. different from non cps neo.

Aiya.....use truck's profile la! More gaya!
