should fit, my brother has 20x10 40 offset, super low disk, with 255x35x20 nitto 555 on ls430 with rolled rear fenders, on uas bags...can touch mufflers on ground and still roll, and your proposed setup only is 10mm further out than his, when you take into account wheel width and offset change, on my bros set up, i can stick my finger between rear lip and rim/tire..with bag deflated all the way

 

Well, The wheels were sold before I got my hands on.

OK, I might buy these set now, they are front 20X8.5 (+26 offset), 20X9.5 rear (+29 offset)
Front tires are 245/35/20, So they are OK, I need to change out the rear, they are 285/30/20 now. What size I need>? 245/35/20??

The wheels were made for SC430, But I think with smaller tires in the rear, they should fit?

 

Put the front tires on the rear & get 225/35/20 for the front.

 

I was thinking running 245/35/20 all around.
So the front needs to be smaller as well?

 

I have a ques
As u know I have a 01 ls 430 I want 20s or 22 I know every says 20s is they way to go but I think it would look kinda small on a 1inch drop in the fron and a 0.8 in the back I might still have a wheel gap now 22s I think will sit right in the wheel wells but my real questin is. For 20s I don't want to look stagger I want a all around nice lip but dunno what off set will work and still flush with the car..also in 22s???
