I have 295/65/15 MT ET Street Radials on the back of my Camaro and Sportsman 26x6x15 on the front (4 ply). They handle weirdly and follow the road crown. I have to constantly correct the steering just to go straight. No problems at the track. I figured I would go radial on the front so I bought a pair of Classic 165/80/15 and installed them. When I let the car down it looked like I had two flat tires on the front! I checked the sidewall and it said "1201lbs @ 44psi" so I put 44 in them. The sidewall still has some buldge to it. My cars weighs 1900lbs in the front so should these be safe? Can I run 50lbs to make the tire rounder?
