hi, im sorry to bother you guys again with the same problem again.
since im selling my rims no one are interested in my rims, so if i change my tires to get the really close diameter with front and rear(the front going to 60 and the rear going to 60),is it the same as same size tires all around?

The diameter of the tire is all that matters, thats the only part that touches the road. ( hopefully ) size of wheel dosen't matter

What is 60 ?

i meant if i change my tires to 235/35/19 and 275/30/19 then the front will go 60mph and the rear will go 60 too...so is it the same as the same size all around?...because i have an AWD..

All 4 tires have to be the same height, I don't know about Lexus but Porsche says all 4 tires need to be within 1/4th inch of same height on Porsche AWD

dealer said as long as the diameters are within 2, then is it going to be fine- -
im on 0.8 off..so is within 2 but i don't know if they are bs or what

yeah that's pretty close, it should say in your owners manual what diameter's you can run

shaking could be due to improperly balanced wheels/tires. check this website out for your tire size calculating needs.

i did the tire balance..and it still happening, and i did the calculating on my set of tires, and it is 3.3 too slow. i know i got mess up, and now im trying to fix it and getting a new right set of tires when someone buy mines. but im still worring that what if it isn't about my wrong set of tires...sigh...still don't know what to do! HELP!!

you know i kinda get that little shake.. but only between 70 and 80 mph... before that it is fine and after that it is fine..

i put new wheels on yesterday, i think their not properly balanced, also i need to get new tires cus the ones i got are not good for winter.

Question... if the tires are not properly balanced will i mess the car up? or will it just shake or go to one side of the other? cus right now it doesnt go to any side, goes straight.. but shakes a bit between 70 and 80...

i have is250 AWD and all my tires are: 225/40/18
