oppps, reversed.. my bad, Fixed*

This tire is weird, it's like driving CC6 comfort with RE003 grip and PS3 wet grip

The grip is good after trying around +-350km.

The Downside is, you can barely feel the road ( i don't know if it's me only or everyone else feels the same).

soo weird...

Hi bro, mind to tell me where you get the tyres with rm159/pcs?
With installation and valve?planning to switch my current p4st to ipro😉

installation and balancing.. for the valve, i'm using the steel thngy, so i didn't change it, no issue till now. The shop is Oscar Tyre, Kota Kemuning, Klang, Selangor.

Price included trade in with your old tyres I presume? I have heard a lot about how Oscar is the cheapest place to get tyres in Malaysia. Just need to make some time to actually go there 😫

Mine usually about equal pressure front and rear or just slightly harder at the front by 1 psi.

Steering feel is fine for me with this I-Pro on my Swift.

my front tyre before this is PS31 and before that is PS3, both of this give better road feeling thn Vitra I Pro.

Welpt PS31 give better road feeling than PS3 even though it's not UHP.

IF this tyre can last 30k km, i will probably buy it again but will go for smaller profile from 55 to 50.

Is this due to the engine weight at the front so even on a RWD, you'd put fronts 1 psi higher? The end goal is to induce less oversteer from this?

But for example, typical stock bmw pressure usually has more pressure on the rears to induce understeer right?

Yes weight distribution is one thing. Another is whether the tires give enough feedback to steering, so usually tires with softer sidewalls I tend to give slightly higher pressures at the front to improve the steering feel. Reducing risk of oversteer is also a factor.

More pressure at the rears may induce oversteer, not understeer. It's similar principle as suspension setting as well. For example, if a car is prone to understeer, you either soften the front antiroll or stiffen up the rear antiroll. But all these are designed as a total package of the car so BMW must have factored in weight dist, suspension setups and traction control behaviour, tire sizes etc2. to finally comes up with such recommendation to get the best balance for its cars.

I felt the same way, It reminded me of Hankook Evo2 but a tad softer?
But I feel the road just fine but I can't compare apple to apple cause on Hankook Evo2 I was on a different suspension.

But Hankook Evo2 was like my 2nd last tires I was using. Before Maxxis iPro, it was Kumho V720.

your tyre size?

so far i've done 500km++, do few high speed corner ( it's really good )

so far it's quiet, comfortable and grippy.. soo noice for cheap tyre, i guess what make it cheap is that it doesn't last long

depend weight at where. yours is regular sedan correct setup. suv is backward due to tall tyre profile and strong weight shift happen

the weight pull away wheel traction at low pressure = super oversteerring.

195/50/15 not my usual size, should be 195/55/15, but they ran out of stock.

depend how hard you drive, maybe it wont last long. tires at this tier last me 2 years +

i think i done about 700km+ already, i can't wait to test on autocross event soon.

Which Evo2, the V12 Evo2 or S1 Evo2? If V12 Evo2, it's actually softer sidewall than the I-Pro. The I-Pro gives better steering feel based on my experience in the exact same car and same tire size (in Suzuki Swift) cuz I changed from V12 Evo2 to the I-Pro.

Yes I am talking about sedan, hatchback, or sports coupe, but the general direction or relationship between pressures and traction still applies the same even in SUV. Whether the recommended starting pressures are harder at the rear could be due to weight distribution or load but the direction of the tire pressure to adjust if got symptoms of under/oversteer is still the same.

v12 evo2, s1 not avail for 15 inch.
can't really compare if sidewall are softer, as i said, im on a different suspension setup.

where is autocross places

last place was maeps @ apd circuit.
depend on who is organising, location varies.

barely any ads/info for any car event nowadays, most event that i saw is SIC/MIMC/Kuala Selangor and Dato Sagor.

since autocross/gymkhana is least popular, is hard to find infos unless you keep track on facebook and such.

Usually which profile size would you prefer for more spirited drive?
