I have an 01 GS300 L-Tuned with original 18" wheels.

I need new tires badly. The current tire specs are:

Front:
235 40 r18 91w
Rear:
265 35 r18 93w

For new tires, using the same rims, do I need to keep the same specs or is there a size that works where I could get the same size for all 4 tires so I can rotate them every once in a while?

Any help is appreciated. I don't know much about tires other than the back ones are currently wider than the fronts and the current tires are directionals.

Oh and the current tires are definitely summer tires. I'm thinking of going with all season tires.

Do you know whether or not the wheels are the same sizes front/rear? If so, then you could go ahead with purchasing the same sized tires all around. For example: When I purchased my 430, the previous owner had 3GS 18" wheels with 245/40/18s. Hope that helps some.

I have 245/40/18s on all fours of my GS430. I don't know the front rim width, but the rears are 18x9.5. Slight rubbing on the right front tire when turning fully. But not too much of a worry.

I use Continental ExtremeContact DWS, and the ride is pretty good.

^^^They are all seasons too...

Turns out my wheels were indeed staggered. I measured the depth and the backs were 10.5 and front 9.5 approximately. I ended up buying Kumho Ecsta 245/40-18's. The rims are MSW type 25 by O.Z. They look decent for a 13 year old car.
