Michelin PSS on Boss 302 Laguna Seca..
- Thread starter Para81
- Start date
If it helps any I couldn't mount 305/30/19 nitto invos on my stock boss rears. And that's after I've been told over and over again 305's will fit 9.5 rims
Stock LS rear wheels are 10". The Michelin PSS 305/30-19 say they want a 10.5" to 11.5" wheel.
With that short of a sidewall I doubt it. Even if someone could the tire would bulge over the rim and would flex in corners. I have 305/30 on my 11" rims and it's about flush with the rim edge.
I have a PSS 295/35 on a 10" wide Laguna Seca wheel. I personally think it fits perfectly. Not sure how the extra 10MM would look or fit.
It will work fine, run 305 PSS and Continental slicks on 10" wheels with excellent results.

He's outside of the Michelin recommended wheel range for that tire size however. Though, I think worst case you would just have some bulge and be wasting your money (about $40) over a 295. I think in reality though you could get away with it just fine, especially if you're planning on getting wider wheels in the rear.

I personally wouldn't go larger than a 295 -- you're not gaining anything. With that said, if I had an LS and wanted to keep factory wheels, I would run a 295 out back and a 275 up front. These are the largest width tires that you can run and continue to gain benefit from the additional contact patch.

I'll try this combo out on Sebring and report back.
I'm running the PSS on my Laguna Seca as well. I thought about doing the 295 rear and a 265 front, but I ended up just doing the stock tire size front and rear. I have dedicated track tires and wheels though so these are just for street use. I will say though that on the street I like these way better than the factory P Zero Corsas. The factory tires were fine in corners but couldn't put any power down without causing major wheel hop. With the PSS tires, she just goes when I nail it and to me there is no lost corner carving performance either. I am very happy with them. The only negative thing I could say is that they are more noisy than the pirellis were but its not too bad.
18's can run slightly different tire sizes than 19's typically. In this case a NT555R (in 305/45R18) is designed for a minimum of a 18x9.5 wheel.
That said, correlation isn't always causation, and a NT555R isn't made for 19" wheels. A 305 in this tire on an 18x9.5 is a perfectly valid fit, and is -as- advertised.
