if you want low profile tires.
they make the car look sexy.

good place to buy them is online.
or used tire shops

 

255/35/20 tire is a perfect size, A couple of us have driven on Falken Tires and Pleased with them, But I do Recommend Toyo Proxes 4 tire, I feel less road and get the best tire grip and handeling with these new tires, There are Toyo and Falken Tires on ebay for between $500-$600 new. In Cali There are alot of places to get tires, lookup custom wheel warehouse they are out of cali and very good to get rims and tires from.

Since your in cali you can order tires I think through my tire guy from fletchers auto and tire

call daryl at 602-861-2221 and ask for a quote

I don't know if you have a fletchers auto and tire in cali but they are great company to buy from.

Tell him Patrick with the white and black monte carlo referred you

 

I agree 255 is the a better choice.
