Hey, I want to get rims for my 99 ETC, but I'm not sure of the tire size with 20s. I know for 18s its 245/45/18, does anyone know what 20s would be? Thanks in advance.

The most common size that you will find for cars is a 255/35/20. Second would be a 245/40/20. I just ordered the BFG KDWs for my 99 STS (245/40/20). I was going to buy the Falken Azenis ST-115, but was told the BFG was a better wet traction tire (I live in Seattle). I have the same tires on my Lincoln and I am happy with them so I don't expect any surprises.
