Default Tire Size Help

Hi can someone help me out on a tire sizes for a 2013 GS350 Base lowered on Tanabe springs. Rim specs are 19x9+32 front and rear.

I checked discount tire and called tire rack but I would prefer to hear from people with a GS.

Thank you,
Martin

An alternative, if you're concerned with rubbing, would be 255/35 R19; these are a little lower (661.8mm), and might be a more comfortable fit on a 9J rim. (9J is the narrowest you'd normally put a 265 on.)

245/35 R19 tires have a nominal diameter of 654.10mm. This is about 2.2% smaller than stock, will make your speedometer read high by the same amount, and will lower your car by about 1/4".

Generally speaking, you want to keep your tire diameter within +/- 3% of the stock size. By that rule, 245/35R19 would work but probably not as well as a 255 or 265. I can't speak to whether or not your tires will rub, but if they were in danger of doing so the 245 would presumably be less likely to.

Thank you Terrence I had to go with the 245 just in case I rubbed. I don't want to pull the fenders or do any type of extra modifications.

Would you rub if the car had 4-5 adults in it?
