i have a 2003 gs 430….will rim size 19x9.5 fit the front and 19x10.5 fit the rear? and if so what are the best tire size to used….i kinda want some meat on the tires incase bumps..that way it won't dent the rims….what are my choices guys..thanks are there any picture of similar rim size out there on the car that i can get a visual of?

 

Those sizes will fit but the amount of fender work needed and tire sizes will depend on the offset of the wheels.

 

Oldie but goodie.

for the 10.5 i would run a 265/30/19 or 275/30/19 for the 9.5 a 235 or 245/30. speedometer reading won't be affected too much, there will be slight stretch, but with the info you have given us its hard for us to help you.

whats hard is you're asking for a pretty wide wheel and a meatier tire so you don't ruin the wheels with potholes etc. My main concern is the offset of the wheels, and how low you are, if its a low offset and your on lowered suspension it could hit your fenders. Yes you may see some of us here run 10.5 and 11.5's but thats mostly with body work, camber, and Stretching tires.
