We have decided that the Javelin will be an autocross machine. A few of the locals are running used track tires (full slicks, Goodyear, Hoosier, and Avon IIRC) on the offbeat cars. I can fit a massive tire under my car so I'm thinking like a used NASCAR 15" tire? I need something gigantic (because massive grip is the only way this beast will turn well) and cheap (because, well, duh).

I can get custom steel wheels (Aero, Summit, Cragar, etc) for pretty cheap, even up into a 15x10.

So where do I get these myhtical tires, how much do they run, and what sizes are going to be best? I have no problem stockpiling a few sets in the garage. Hell, I may even buy a tire machine...

A very small one. Lots of road courses though. I know one of our local AX's uses Formula Continental(?) tires.

This guys been in business for over 25 years. Has a very good rep with everyone that I know that has bought from him. He always did my friends and I good when we used to AutoX a Capri in E/P using slicks.

Thanks for the link, but man that's a horrible website. They don't actually list any of the sizes in stock or prices, compounds, etc.

Are you limited to tires that meet "DOT" regs? (lots of clubs around here won't allow Bias ply slicks, only DOT-R tires like Hooser A6 or Khumo V710)

For 15's, get some Diamond racing wheels and go look at "American Racer" tires (there have been a few threads). They seem to be at least 90% of the performance of Hoosiers with only 50% of the price.

Make friends with the local GASS racers (old guys running NASCAR-style race cars) down at PIR, Kent, the Ridge, etc.

Also the NASCAR West racers come to Portland once a year.

There's also the local GT1 and Trans-Am teams.

In reply to Apexcarver:

The rules I'm running under have one rule, that it's not a Porsche. Ideally I'd like to get it into a pseudo-CP trim and run the modern ProTouring races as well. For now some cast-offs of whatever flavor will do.

Ebay seller USDRRT search inventory in his store: http://stores.ebay.com/Race-Tires-USDRRT?_trksid=p2047675.l2563 or send email with what you're looking for...

Middle/end of the season is always the best time to buy...

It's best to call or email. I think he has such a large, rotating stock......it would be a full-time job for 1+ people to keep it up-to-date.

Call 'em. I've ordered from there before. Great prices, good inventory, fast shipping. Will use again.

In reply to Raze:

Hmmm... He has quite the selection of 225/45/15 R6's. Plugging that into the tire calculator shows that they would be a little shorter than stock, which since I have a 2.87 gear would be a good thing. I don't know if that's "enough" rubber or grip though.

Anybody run 225 R6's on an ~3260# car in autocross?

If I go wider they might not heat up (in R6 compound), but with the narrowness, will they overheat?

Hoosier 3035's that are used on the SCCA GTA stock cars would probably work well for your application. Very sticky, are 27x15x10. New about 600 per set, used 100-200 per set.

You'll be able to heat quite a bit wider than a 225 R6 in the Javelin.

I love scrubs!

I usually just pick up used rally tires from teams and they will last quite a few rallyX, and then after that they become decent street tires (compared to bald summers) but after that they are even more worn and they become great drift tires. (they smoke real easy)

reduce REUSE then recycle....

I recently bought a set of used Toyo R1s for $100 bucks from a seller here on GRM to autoX my 300zx rallyX car. The Toyos were well worn, but the ZX instantly went from suck to awesome over the BFG Comp T/As I was using. Viva la cheap used racing tires!

I've learned when it comes to race/autox tires, any race tire is better than a street tire in just about every way, even at the very end of it's life...

A 10" slick isn't really all that big. I just bought a full set of American Racers in the M-28 compound (Hoosier A6 soft) for $132 a pop. They're 23.5/10-15, very very short.

Used tires, I ask my old roundy-round racing friends.

Isn't there (or didn;'t there used to be) an operation in the upper Midwest that specialized in used race tires? It has been several years since I bought from him, so I honestly don't know.

This time of the year, right after the SCCA Runoffs there always was a huge glut of used race tires available through him. And used autocross tires were plentiful the week following every event on the National tour.

It was always nice to get a set of Hoosiers that somebody had only used for qualifying and then replaced with fresh rubber. I got several sets with almost full tread depth by just making the phone call to him.

A 23.5/10/15 would be ideal for me. The shortest I've found so far is a 25/10/15 which would be okay.

I think they're front tires for some kind of Mod.

New roundy-round tires: http://www.americanraceronline.com/Asphalt-Track/modified.html

If they cost 2x as much as a used tire, but last 2x longer...well you get the idea.

Aaaaaand that's that! Thanks fellas, but I just got a set of 17's for free, so now it's time to find 3" adapters.

Anybody ever see FR500's on a Javelin before?
