Guys can I do 255/35/20 on a 2007 LS460

 

sure you can! but why..? check out 1010tires calculator

 

245/40/20 is the recommended plus size for 20" wheels. if you go with a 10" wide rear wheel, you would use 265/35/20 or 275/35/20

 

I was told 245/40/20 will rub in the back, so they will go with 255/35/20 the rims is 8.5 would that be a problem

 

i have 245/40 front and 275/35 rear on my car with 20x10 staggers in the rear and they DO NOT COME CLOSE TO RUBBING WHATSOEVER! I also have all season tires that are not "squared" shape like some tires. They don't know what they are talking about. I have 31 offset wheels which put the wheels a little further out and still no rub. What is the offset of the wheels you are getting, that plays a part. Unless your tires are sticking out past your car, you need 245/40/20 tires..period!

Side note, i was worried at first about rubbing on the inner part of the rear struts, and i have about 4+ inches of clearance between the tire and the strut...also, when the suspension moves, the tires lean in and will clear the outer fender..you have nothing to worry about, seriously!

 

the offset is 13
