I need a set of okay tires with some decent tread, 255 wide minimum, I'd prefer 35-45 sidewall and R 18

i got 265 35 18 tires. Nitto 555 with only 20 miles on them. Just giving you some options.

I have an almost brand new set of Dunlop Star Specs. 275/35/18. Paid $1300 for them new. They maybe have 2500 miles on them and 2 autocross sessions.

Let them go for $900.

I need something to just get me rolling, in the 400-500 dollar range

Ah ok. Yea mine are probably overkill then.
