boss can u explain to me king pin inclination

Hi Sifu, need advice. My tyre sidewall flatten abit as I didn't notice I'm driving on a punctured tyre.

Is it still safe to drive on this tyre ?

i put smaller rim, will improve/worsen king pin rite.
how about negative offset

Is Michelin Primacy SUV still the best tire for SUV? My tire is about 3 years old with 60k mileage but the "bunga" still nice and still looks okay..not sure need to tukar or not.

아아아아 scrub radius.
does it improve or worsen uturn distance

The recommended tyre pressure for my car is 220. Everytime I pump 220, then I check again immediately, its down to 210. So I pump 230 so that when I check again, it will be 220. What is your comment on this? TQ

Bunga ada.. But cracking I don't know how to see hmm..

There are reason for odd sizes as to increase the traction and high speed/cornering stability.
Most RWD cars & performance rides does got wider size for the driving wheels

My fathers BMW e90 320d is a good sample (Original FR 225/45/R17, Rear 255/40/R17), changes 1 time same 225/45/R17 for all tires after that regretted.
Why? -> Driving dynamics really felt weird and sway a lot in the rear when picking up or enter corner fast, especially rainy days even felt more worse.
Only good is fuel consumption might be better a bit as it is lighter.

Unless you drive very slow (Which i doubt for most continental drivers) there are reason why the engineers put in the odd tire size at first.

You changed aftermarket rims also wont be perfect if you add in spacers unless original rims from BMW.
Personally for Continentals stick to original setup is the best. Once you mod, never ending stories, later upgrade this rim, that rim, change tire size in the end most revert back original sport rim/tire size still the best.

i silly one becos reduce rim and reduce tyre profile.
replace rim 5mm negative offset, now confirm very positive scrub.
turn steer movement became untidy. unlike ori

tire & driver related

if u watch youtube review, then that is a biases review, cz they got free donut by Continental Malaysia for most YouTubers.

Learned the hard way regarding Hankook Ventus Prime tires.

Lousy af. No more. Aside from online user & Youtube reviews, need to consider feedback from tire shop & other users met in RL.

All in all, need to consolidate all of those with a pinch of salt.

I've tried both 16" & 18". 205 & 235.

Similar lousy sxxt. Wider tire behaved even worse.

aduh....

unfortunately last nite I had a tire puncture, so this morning pasang the VP4 already.  going from 45 to 50, cornering feels a bit spongy, esp if do sudden movements. Not liking that. But can adjust driving style, so far no rain yet. Definitely cant spirited drive like before, need to dial down slightly.

road noise, feels like not much improvement over my 7 year old rubbers. 

But new rubbers sure absorb road pimples better.

So after a few days of driving with some wet stints, its obvious going down from 215/45 to 205/50 has a big impact on the limits of cornering and aggressiveness of switching directions. Needed some time to re-wire my brain to the new tires. Slow~ slow~ granted I'm not a performance type or driver, just used to the earlier profile for 7 years so its engrained into the butt dyno. Grip is good enough for my car. Didn't expect much more.

And the noise seem to have gotten less than earlier. As expected, 50's absorbs the road surfaces better. So, so far everything seems to be within expectations.

Hopefully can last at least for the next 5 years.
