On road tires

Give Losi Rally premounts a try as well. They are good for 103mph for sure.

I bought mine at Leisure Hobbies at Joliet IL. phone # 815-439-1477 and also they have some here but only on 45 shore # 813-920-2428. http://ipanemasports.com/default.aspx
I tried a 40 shore and it is softer, the more you use it the softer it gets, kind like slick tires for drag racing.
Also it cost 30.00 for a pair.
