I had been running a 325/30R20 on my Forgestar F14s on the rear of my Shelby without any mods or rubbing for 4 years. It was time to buy new tires by the end of the fall last year, so I starting looking at tires online. I knew there were very few companies that offer anything over a 305 and I didnt want to get a narrower tire so I started looking at wider. Michelin Pilot Super Sports had been getting great reviews from guys with big power, .... they don't make a 325/30R20, but they make a 335/30R20....and wider is always better...lol. There is a 325/30R20 Michelin Pilot cup road race tire, But I didnt want a road race tire To run these tires, I would either have to get new rims or get mine widened. With our dollar so low and Me having expensive tastes in rims.....I decided widening my rims would be the best way to go. After some careful measuring, I decided to get my 20x11s widened to 11.75, which would be in spec to run the 335s ( 11.5-12.5). I sent my rims to Weldcraft in Michigan to get widened and 6 weeks later I got them back. The 335s are really wide......alot wider than the 325....but I read Michelins run wider than other tires here's a pic beside the 325...The 335 is .75 wider Mounted Mounted width....sorry for bad pic...I was trying to hold the tape and snap a pic at the same time Beside the front 255/35s Mounted on the car.....fits like a glove. I really have to clean them To fit these, I removed the bump stop brackets and the shock dust boots. I have enough clearance that I can fit my fingers between the inner fender and the tire all the way around...I have small fingers though. The drivers side is also a bit more snug on my fingers, I will have to adjust my panhard bar a little bit. It is still not nice enough to get the car out of storage yet so I cant road test them right now...but we finally got some nice weather this week and the snow is melting fast....I will try to get some pics from behind the car soon.
