Using higher aspect ratio tyres on a Supra.

Recommended Posts

My Lexus GS300 wheels have been refurbished and I'm looking at what tyres to use. The wheels are 18" x 8.5" front and 18" x 10" rear.

I believe that the usual rear tyre size used on these wheels when fitted to a Supra is 275/35/18 but I'm considering going up a size or two on the profile.

 

Does anyone know if 275/40/18 or even 275/45/18 would work OK or would I have trouble with the tyres fouling the body work?

 

The car ('93 RZ auto) is on standard springs and yellow bilstein shocks.

I'm OK about the gearing being raised and I think I'd quite like the not-so-harsh ride compared to the 35series tyres I'm using currently.

 

Any thoughts?

I've got 285/35 which should have a similar effect to 275/40 (haven't checked the maths!). They rubbed the arches when the car was really low, I've had them rolled at the rear and raised it about an inch - it's still lower than when I had the standard yellows and springs though and is now fine.

When I put 19's on mine I kept the same profile as when I had my 18's haven't noticed any problems since. I didn't want to drop to a mega harsh profile either......
