Change gears or tyres?
George:
I think it has been said a time or two here but you could gain performance with less tire. I would compare tire weight. The more you can reduce the rotating mass the quicker the car will react and perform . I have tried several Goodyear and Hoosier sizes and nothing has been quicker than the GY 2885. I run Hoosiers now because we live 10 minutes from a Hoosier warehouse. Good luck and have fun. George
JrFuel Hayden:
George, do you mean D2585, Goodyear 31x12x15 that is 22.6 lbs ? What Hoosier are you happy with ?
I still have the D2585 available.

Oops, yes Jon its the D2585. Now that we are running a blown combination the weight disadvantage isn't such a big deal. I have run well with the Hoosier 30189652. I am not sure if is a good catalog number . I had bought a set of the 31.0/12.0-15 #18225 and went back to the warehouse and got in contact with a racing rep with a complaint of the tire being heavy and they sent me the set without a charge. As I recall it was 5lb lighter so it was about 25 lbs. As I understand it Hoosier built the #18225 as a JR fuel tire ? https://www.hoosiertire.com/pdfs/jrfuel3112015.pdf
Please send me a quote on a pair of the D2585 shipped to a commercial address 62703. Thanks George.

just for fun I ran tire change thru drag simulator.1" chnage in tire =.005 @60',320 rpm @ 1/8 and 295 rpm @ 1/4 mile. Now this was with 4.11 gear and more motor than OP. IMO its very little.since gear set is half cost of new slicks or even less if need wheels,I would think gear change would be best bang for buck.
