Please advise me,,, If these wheel fit on my 06 GS430.

And one more stupid question....

I dont understand why people use different height tire... (35/ 40)

Thank you,,

 

The second number is a % of the first number. So since you have staggered tire sizes, you would need a different aspect ratio to get roughly the same height.

Those tire sizes are WAY too big. You want to keep it under 3% bigger than stock tire size. Most people here run 245/35/20 and 275/30/20. However the front is slightly over 3% and therefore, "overspec", If you have particular rough roads to drive on like the streets of LA the extra cushion would be nice, even if you may rub slightly. I personally would go 235/35/20 and 275/30/20 which are much closer to the same size.

 

see the wheel thread so you can learn. that's the best way. Then you can ask the questions to get a good feel for exactly what your looking for.
