345/30/19 on 2011 Grand Sport
<div style="text-align:left;"><strong>345/30/19 rears with 285/35/18 fronts Michelin Pilot Sports . Will they fit on my stock Grand Sport. <br /><br />Just bought a GS , these sizes from what I have read should fit real nice on my stock rims. The 325’s on rear are shot🙃 wanted to order today. Has anyone gone too the 345. ?? I also read u could bolt on 355.s but not sure of that either??? Thanks </strong><div style="text-align:left;"></div></div>

My base with Z06 fenders had 345/30/19 on the rear Nitto NT05R. I swapped over to the Nitto NT05 for better street manners and went with 335/30/19. My car is also lowered quite a bit and did not have fitment issues. I have replica Z06 wheels though so not sure how much this helps.

345/30/19s fit without issue on the stock wheels. Been using them for years. Mixed with 285/35/18s will work as well keeping traction control from activating unnecessarily.

I'm wanting to run 345/30x19 Rear 19x12 +50 offset Wheel AND 285/30x19 Front 19x10 Wheel READ AGAIN LOOK TWICE
My only choices of tires on rear are Nitto Invo and Michelin Super Sports
ANY problems with traction control
IF I was to 325/30x19 Rear (OE Grand Sport/Z06 size) I have much bigger choice of brands but I'm thinking 345 on my new
ForgeStar Wheels will be a better LOOK ?????

Tire choices for 345/30/19 run-flat's is limited to one tire, Michellin PS ZP, which seemingly is never in stock or on back-order at Tire Rack.
I gave up and went with Nitto Invo's and AAA plus a Slime Kit. YMMV

345 NT05R in the rear to give you an idea of what they look like.

If you want to go even wider, 355/30/19 will also work on oem rear wheels. They'll match with 285/35R18 fronts and give you no ah/tc issues.

I had the 345 Nittos on my GS. They had way less traction than the Bridgestone Pole Position RFs they replaced. I’m not stock though, header, CAI and tune.
Only got about 10k out of them for spinning so easy, even in straight line pulls with no shifting in the 1st 3 gears.
But no fitment issues. Now have Michelins in the stock size, much better traction, almost as good as the Bridgestone’s. Wear appears good too, about 5k on them so far.

No traction control issues with either setup.
You should check and compare the offsets of your aftermarket rims, to ensure all dimensions are the same as stock, or all of comments will not matter anyway
