Putting on Some new tires and wanted to see how big I can go...looking at some 315/30/18 would they fit?

I run Toyo tq 315/35/18 on my lowered stock rimmed z06. They fit fine, and have descent traction.

depends on your wheel size.

I run the Toyo R888 in 315 on my factory z06 wheels, lowered on longer bolts with no issues.

Really? You don't say?

I'm currently running PS2's 315/30/18 on 10.5 wheel which are fine lowered on stance coilovers. Just ordered the same size in toyo R888'S ... you will be fine

315/30/18 michelin pilot sport cup I needed a spacer, kuhmo v710 fit fine, with hoosiers I need a spacer. Hoosiers are racing slicks

Where do you all find these tires? I look on tirerack, discount tire, nitto, bfg, and even toyo website.

A lot of big tires in 17/18" sizes have been discontinued over the past few years. The only 315/30/18 street tire available today as far as I know is the BFG Rival... but you'd have to run that at all 4 corners on a C5 since they don't make Rivals in any useful 17" size to pair with it.

SEARCH next time. Jeebus.

Stuffing wide and wider low profile tires on a particular wheel width isn't going to give you a whole lot. Sidewall will start to bubble out which does not look good IMO and it negatively affects handling. 295 is stock on the rear wheels... I would go up to 305, but that's about it. Tire specs list their "approved" rim widths limits and their ideal width as well.

While this is true, two manufacturers with the same stated size tires will be actually different, hence this discussion. My Togo 315's are no wider than my M/T 305's. Also, some sidewall BUBBLE will help straightline traction a bit as the tire will give. Which is what most are looking for.

I'm putting Hoosier drag radials 315/30/18 you think I will need spacers?

I run 315/35/18 Toyo TQ Drag Radials on my stock C5 18x10.5" Z06 wheels. I also run them on my 18x11.5 CCW 505a's. I am lowered on stock bolts. No spacers.
