I tire tested this last Time Trial at Buttonwillow. I'm running 23x9x15 canti slicks in the following:
Goodyear = R430 Compound Hoosier = R60 Compound I scubbed both new sets of tires in 1 month ago at Laguna. I then ran the Goodyears in session 1 on Sat and Hoosiers in session 2. I reversed the order on Sunday in order to be fair about track temps. Both days were low 80's ambient. Saturday I was 1.8 seconds a lap quicker with the Hoosiers and Sunday I was 2.2 seconds quicker. I guess all it means is that the Hoosier compound was working better for me that weekend. Does anyone know if Hoosier and/or Goodyear changed their rubber formula significantly over the last year? Last season the tires performed nearly identical. Anyone with similar experiences? Bill P. |

Hi JP and John,
I run R45's for Auto-x and for tracks easy on tires like Laguna Seca and I run the R60's (it's now R55's I believe) for the tracks that are tougher on tires. The tire compounds go something like this for the canti slicks: Softer to Harder -------------------- 210 Goodyear (No longer available) R35 Hoosier 250 Goodyear (Newest offering, replacement for 210) R45 Hoosier 430 Goodyear (Most common Road Racing compound for folks partial to Goodyear) R55/R60 Hoosier (Most common Road Racing compound for folks partial to Hoosiers) 600 Goodyear I've used the 210 and a now discontinued 270 Goodyear compound for auto-x and the R45 Hoosier compound for auto-x. The 210 Goodyear's were definitely the stickiest but are no longer available. I don't feel any difference between the R45 Hoosiers or any of the other Goodyear compounds other than I have observed that the Hoosier seem to wear a little better than the Goodyears. Also the Goodyears have a much stiffer sidewall, so turn in is quicker on an auto-x course. On the track for whatever reason the Hoosiers and Goodyears feel the same for steering input. The R45's heat up in 1 lap on the track. The R60's heat up in 1 lap as well, but I also help scrub them to temp during the warm up. Lots of data...... (IMG:style_emoticons/default/blink.gif) I'm keeping track of heat cycles on each set. I'll report back with how many heat cycles you get before the tires go off pace. Thanks, Bill |
