I've run a set of 275/40R20 NT555R's on my bolt-on L99 and went 1.85 with them last year. They are a definite improvement over stock tires, best I could go on stocks was 12.7 on a 1.92 and best I went on the 555R's was 1.85 as mentioned.

All 20" DR's are a little pricey, so also check around locally on CL and on www.tbssowners.com (Trailblazer SS) sometimes good deals on there. I've DD on mine in rain and they were like stock.

I'm now also running a set of 305/18 NT555R's on 18's, not stealthy, went 1.66 on them I have a converter now. I would only DD if you have a short commute like me, mine is 5 miles one way.

Comparison:
