I've been doing a lot of work on my GN the past few seasons and I'm already seeing major limitations of my 235-60-15 rear tires. They're mounted on 15 x 8.5" Centerline Auto-Drag wheels and I want to keep those wheels; it's a look I've always liked. But with the rather modest performance upgrades I've done thus far (see signature), if I do a brake-stand, the tires begin spinning, just after boost barely begins to register with the OEM dash boost lights. Needless-to-say, that's not going to result in good launches, and I'll just burn rubber even more as I upgrade the fuel pump, hotwire it, and upgrade fuel injectors and such.
A theoretical ideal size would be 255-55-15, but that doesn't exist in reality...and I've researched that the maximum recommended tire size to put on 8.5" wheels is 255; so I'd like to go with 255-60-15.
Some questions:
1. What are some good tire options for that size, that will help the launches and not just burn rubber?
2. I currently get some minor tire rubbing the fenders when I hit a big bump or big swoop in the road, and that's with 235's. I've upgraded the rear springs to variable-rate springs, which helped a lot with the rubbing, but I still get a bit of rubbing...I'd rather have NO rubbing. I imagine that upsizing from 235's to 255's is only going to make it worse, so what are my options, keeping my existing wheels? I hear about rolled fenders...how is that done and does a body shop charge a lot to do it?
