I decided not to get new rims this year, but my tires don't grip very well so I do want to get some better ones... was thinking about 275/40R20 https://www.americanmuscle.com/nitto-nt555-g2-challenger.html I'd put those on my stock srt rims in the rear, and I was thinking about leaving the stock 245s on the front rims. Is that a bad idea? Should I get new front tires while I'm at it? If I do, should I stick with 245s or go bigger? I put the car away for the winter. I haven't taken it to the track yet, and probably won't this year, but plan to next summer.
