My friend just some some Rota's 18x9.5+20 all around for his Z and he is wondering what tire size he should get. He is planning on putting some spacers... What size of spacers and tires should he get? all help is appreciated thank you...

 

im runnin 275 tires on my factory 18in 8.5 rear wheels (30 or 33 offset?)
with a 25 mm spacer, i had to roll my fender but its sits well. also have tein stechs, sits better

 

How aggressive does he want ? Does he plan to roll fenders ? Does he want to run stretched tires ?

Need to know these things, cause without rolling the standard 275/40 rear tire will start to rub with only a 5mm spacer. The front will start to rub shortly after a 5mm spacer with a 255/40 tire installed.

 

^ I don't think he'd rub with 275s in the rear for a 9.5 +20 rim. I'm running 285s on a 19x10.5 +23.

The fronts might rub a little if you run 275s up there though IMO
