jracer98 Posted April 13, 2011 Report Share Posted April 13, 2011 TMS President Gossage said today (on Dallas sports radio) that he is adding something to the upcoming Indy car race. This Friday, they are testing sportmods on dirt tires on the legends car track that's the "connected" front straight and pit road (1/4 mile) HMMMMMMMMM...... jay Quote Link to comment Share on other sites More sharing options...

Racer26 Posted April 13, 2011 Report Share Posted April 13, 2011 I do not think the dirt tires will hold up. Were you at the free practice and test they had last weekend on DIRT tires? Just asking.... Quote Link to comment Share on other sites More sharing options...
jracer98 Posted April 13, 2011 Author Report Share Posted April 13, 2011 (edited) The practice is this friday. I am not sure exactly when the test was done but it was done recently by the Hoosier dealer.... jay Edited April 13, 2011 by jracer98 Quote Link to comment Share on other sites More sharing options...
sandersracing Posted April 13, 2011 Report Share Posted April 13, 2011 I was not at at the practice. There where some sports mod that tested the dirt tires at thunder hill and they did not last long. Quote Link to comment Share on other sites More sharing options...
TheCloser Posted April 14, 2011 Report Share Posted April 14, 2011 i know they didn't hold up that well at corpus. but i doubt the track at TMS is nearly as rough on tires as corpus Quote Link to comment Share on other sites More sharing options...
rebelracewriter Posted April 14, 2011 Report Share Posted April 14, 2011 Back when Owen had one of his Big Dog shows at THR weren't the big mods on dirt tires.....The hard compound American Racers before IMCA switched to Hoosiers?.....I don't recall much tire wear then.....but I've slept a few times since then...lol Quote Link to comment Share on other sites More sharing options...
supertx Posted April 14, 2011 Report Share Posted April 14, 2011 (edited) Steve miller ran dirt tires led up to the last few laps and the tires gave up Edited April 14, 2011 by supertx Quote Link to comment Share on other sites More sharing options...
97car Posted April 14, 2011 Report Share Posted April 14, 2011 The sport mods are on a different tire and compound, Wayne Brooks ran the American racer at the big dog shoot out also and placed pretty good and those tire didn't look that bad.

jracer98 Posted April 16, 2011 Author Report Share Posted April 16, 2011 (edited) here's what I saw... fast lap was 16.20/30 6.20 to 6.50------->7200-7400 but several were pretty "flat" at the flagstand some pretty feathered tires in 3 or 4 10 lap sessions some sway bars, some no a lot of stop and go--->high static rear% and rear biased brake mc's (?) maybe 8 cars jay Edited April 16, 2011 by jracer98 Quote Link to comment Share on other sites More sharing options...
jracer98 Posted April 16, 2011 Author Report Share Posted April 16, 2011 also, while most of the track is flat, the nascar front straight is banked. It is unusual and a suspension challenge in that there is no transition up on to the banking halfway thru 4 and down off the banking halfway thru 1. The cars looked cool under the lights running in front of those big stands. jay Quote Link to comment Share on other sites More sharing options...
jwmbishop Posted April 21, 2011 Report Share Posted April 21, 2011 I think I would rather run slicks on the dirt than dirt tires on asphalt - seems the dirt tire would fall off too fast and "disappear" unpredictably... Quote Link to comment Share on other sites More sharing options...
jracer98 Posted April 21, 2011 Author Report Share Posted April 21, 2011 (edited) I predict that someone will take a page from the scca dot tire deal and take a set of tires to a tire tread "truer" machine--->basically a tire lathe. They will have 90% of the tread shaved off . The tires will be faster and run cooler. BTW, the dirt car series Marc is running now uses takeoff 10" Hoosier asphalt slicks->on dry slick, the cars are all in a wad because no one can really get away. The tires are only $30 each but the rub rail and body dollars are going up jay Edited April 22, 2011 by jracer98 Quote Link to comment Share on other sites More sharing options...
