Sterling Doc Posted October 27, 2009 Share Posted October 27, 2009 Planning on the 9 hour enduro at Road Atlanta in December. I have a choice of 15 or 16" rims for enduro purposes. Since my beloved RA-1 is on National backorder in both the 225/50/15, and 245/45/16 sizes, I've been evaluating my options: R-888 in the same sizes (practical choice, but not my favorite tire) Nitto NT-01 in a 225/45/15 (not sure the 245/50/16 will fit?) BFG R-1 in a 245/45/16 (tempting, but will it make the distance?) As the track is not very abrasive, and it's a lot of tire on a light car in cool conditions, I'm tempted to gamble on he R-1's. They have a reputation for better longetivity then the Hoosiers. 'Course if it rains, we'll have to ahve a back-up (not so with the R-888) Am I crazy?

robbodleimages Posted November 1, 2009 Share Posted November 1, 2009 R1's are as fast as hoosiers and last nearly as long as Toyos. I would definately go that way. Quote Link to comment Share on other sites More sharing options...
richard migliori Posted November 13, 2009 Share Posted November 13, 2009 Don't you have to run the spec tire of your class? Unless you change and run ES? I believe the rules for endurance racing is that you must comply with the class that you conform to. We ran a FFR spec cobra and have to continue to follow those rules while running in EO.

Richard you just have to make sure you're legal for a different class that still folds into E_ . In Erik's case he could use Performance Touring rules and use whatever he wants equipment-wise, so long as he doesn't go over the points limits for whatever PT classes fold into E2 for your FFR Cobra I would look at using the Super Toruing rules if they still fold into E0 Quote Link to comment Share on other sites More sharing options...
robbodleimages Posted November 13, 2009 Share Posted November 13, 2009 My read on these rules says that AI cars are not required to run the Toyo spec tire. The car otherwise needs to be AI legal. Quote Link to comment Share on other sites More sharing options...
Sterling Doc Posted November 13, 2009 Author Share Posted November 13, 2009 Enduro rules specify that you can use whatever DOT tire you like on the class legal rim. For me, I will be running under GTS-1 rules which are strictly power to weight, so I have unlimmited tire/wheel options for this race.

kbrew8991 Posted November 13, 2009 Share Posted November 13, 2009 I always forget about GTS with stuff like this Quote Link to comment Share on other sites More sharing options...
Sterling Doc Posted November 13, 2009 Author Share Posted November 13, 2009 Since 944 Spec, Cup, GTS-1, and PT can all make to E2, we have a huge range of options, the least restrictive of which is GTS-1. One of the benefits of running a 944 (that and the 21 gal gas tank ) Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted November 13, 2009 Share Posted November 13, 2009 maybe we need to revist that 10 gal restriction for E0-E3 Quote Link to comment Share on other sites More sharing options...

'Course if it rains, we'll have to ahve a back-up (not so with the R-888) Am I crazy? 1 - set of R1's won't last....well let's say they won't have much grip somewhere after 1/2 way.......remember enduro's are about consistency....and being there at the end...and like you said if it rains the R888 is ready to go in most cases.

Sterling Doc Posted November 13, 2009 Author Share Posted November 13, 2009 As a hedge against being crazy, did get a back up set of R-1's mounted, and have a set of 15" R-888's for rain. Now that we can change 4 tires in the pits, risking a tire change is not such a big deal. Quote Link to comment Share on other sites More sharing options...
bnewport Posted November 15, 2009 Share Posted November 15, 2009 I'm running 4 225/45/15 NT01s which should last and have a set of 225 15 R888s if its wet. Quote Link to comment Share on other sites More sharing options...
Karl Posted November 16, 2009 Share Posted November 16, 2009 the 225-45-15 ra1 we ran last year on out 2450# 165 fwhp e1 car made it through the race. The lf tire was a little out of round, very near cord, and we were out of the running for an hour with a wiring problem. If I was to do it again I would plan on a tire change for at least that corner. Quote Link to comment Share on other sites More sharing options...
