Default Front Tires OEM 92Y can i put 96Y

Hi all, yesterday i hit a pot hole, the lip of the rim put a slit in the tire, tire caput !
OEM front tire is 92Y, is there an adverse effect of putting a 96Y, i.e. harsher ride ?
Thanks in advance

No, should be fine as long as it is not XL rated. The 96 is the load index and Y is the speed rating. 96 means, how much weight that tire can handle, which is 1565 lbs while 92Y means 1389 lbs. If you have an 'XL' next to the new 96Y then it would mean, it has extra reinforcements in the sidewall for superior handling. Our stock OEM tires are non-XL rated for better street driving, but don't handle the load well (sidewalls start flexing) at the limit like the XL versions do.

If your other tire is OEM then make sure your 96Y is not XL in order to keep the handling consistent turning left and right. If this tire is XL rated, you will have to buy the other side with XL rating as well in order to make sure you have same behavior on both sides. Otherwise, I don't believe 92Y on one side and 96Y on the other side would make any significant diffference.

No, by all means replace them with the 96Y load rated tire. Why Lexus put standard load (92Y) tires on a performance car is beyond me. You will experience superior handling with the XL tire. BUT, and this is a BIG BUT, DO NOT replace only one tire, replace them both. Never mix mismatched tires on the same axel.

In regards to the above post. 92Y = SL (standard load) - 96Y = XL (extra load) in a 255/35/19 tire.

Agreed. If it is like that where the new tire is XL while the other side is OEM non-XL then yes, both tires need to be switched to XL rated tires (better for handling and confidence inspiring drive as well). It will be a very bad idea to have XL one side and SL on the other side of the axle as it will give unpredictable handling (especially in rapid transitions).

Thanks for your inputs guy's.
I bought a used tire 92Y wich match the other side, both front are the same.
The guy i bought the tire also have 2 almost new tires with 96Y, at a very good price.
That is why i asked the question, wanted to be sure it was ok.
So then the 96Y would be fine as replacement tires when the 92Y comes to there end of life, if i read correctly.
Thanks again guy's, really appreciate it.

Yes, 96Y should work out better than the OEM 92Y since the 96Y (from what FlowRider posted), are XL rated tires, which means they have reinforced sidewalls for crisp steering response and the sidewall does not deform under heavy load.

Personally - I would NEVER buy a used tire. Especially on a HiPo car I trust the tire is the same brand and model as your other tire?

Some of you folks may not know, or even care, how important a tire is to the overall safety, drivability, and handling of your RCF

This car is NOT a Kia Rio

I agree. This is not a car to save money on tires with.
