I bought these wheels for my 07 IS250 with lexus offset. The fronts are 19x8.5, rears are 19x9.5. I was thinking 245-35-19's and 275-35-19's in the rear. Can i get away with 40 series sidewall? What is your recommendation on tire sizes? I dont like the stretch look either.

I forgot to add that i will be dropping the car 1.4 front and 1.0 in the rear with Eibach springs.

 

Check the specs on the tire on tirerack for the overall diameter of the tire itself...See how close you come to the over all diameter of your current 275/35 rear tire...if its a touch under like .2 or .1 or over by .2 or .1 then you should be fine..

I doubt it given the current specs tht I know....running a 40 series with a 275 (if you can find one) will more than likely rub
