Tire width max on stock rays
 

Hey guys,sure this has been asked but how wide of a tire can be run on an 09 z with rays 19's,iam also running 15 mm spacer on rear,was thinking about 295 re-11s

F:265 r:305

305 is about the widest you can go on the rear - for the track I run a set of 4 rears with a 20mm spacer in the back. 295/30r19 square Toyo R888 - fits on the front with -2.8 camber, about an inch and a quarter drop on coilovers. No rubbing

285/35 305/30 front and rear
Edit 305/35 my mistake not 30 ratio

20% overage.
