Default My slicks are shot should i run free 29/10.5/15

My slick got a hole in it last weekend at a big race. Lots of stuff on the ground, three people that i know got flats. I have to run again this weekend. I have some Freeeee, Hoosier 29x10.5x15 Slicks that i can put on. What do i have to beat to get them to fit? I do have Bogar Rims with the correct offset i think 7.5 inches so i'm wondering if i will have room. I test fit the tire unmounted and i have clearance front to back i'm just not sure about the inner fender well. Also i how much will i loose going from my 26 incher with 3:73 gears going to the 29??? I just don't have the money to buy a new set of 26 inchers for the rest of this year when i'm going to do a gear change next year anyways and go to 28 inch tire. Thankyou

Going from 3.73's and 26" to a 29" slick is gonna be a pretty big jump for ya. Did not see what your setup is (motor/tranny), but I would say you are a bolt on guy if running a 26" (not trying to assume anything, but just taking educated guess since i can't see your sig right now while I am typing)

So, you are gonna lose some probaly a little bit of everywhere...bottom/mid/top end...that 29" tire is quite a monster.

Clearance..that is where you have me...this is my first go round with the FBodies, as I come from teh Ford camp. That being said, when I went 29" on our Fox Body Mustangs, ALOT had to be clearanced, and looking at some of the FBodies my shop has had lately, there is a little bit mroe room it appears on teh Fbody over the Fox Body, but not a whole bunch more. I would think that you would get into some inner fender clearance issues.

But, it is like this...I would not jump up to the 29" without changing the gear out, but that is my .02, and I know you did not ask that. And since the tire is free, guess it would not hurt to try it....

Well, after reading your sig, I see that you are more than a bolt on guy.

Still think the 29" is gonna be too much tire for your setup without changing the R&P out. But, since teh tires are free, and a R&P is cheaper than tires.....give it a go. If it does not work, you can always step back down....

Hopefully someone that HAS put a 29" tire on a FBody will chime in for teh clearance aspect of it though...

I've got some 315/60/15's out here (29.8") and there's no way without a super BFH or mini tubbing it. Same here, the going from 26" to 29" you really need to atleast jump up to 4.11's.

Once you get them mounted I think you will see it is not worth the work to get them to fit.

I have 29.5's on my car and they are HUGE!

I went from 28.0" Hoosiers to 29.0" and regret it. I had to do some cutting and banging on my fenderwell to get it to fit. The 28" fit perfect, rubbed a tiny bit on the inner well, but not too bad.

Maybe you could sell the hoosiers and get a set of 28's this year. One inch really is a big difference with tire size. With 3.73 I prob wouldn't even go to 28's. But free is free and it shouldn't hurt anything to try them.

Thanks all for the replies. I test fitted one. With my Bogart rims with 7.5 inch backspacing the fit with triming on the bottom back of the wheel well corners, and the lower front of the wheel well i had to just bang in a bit where there was a minor rub. Yes they are huge in there. They are just temporary until i can get something new. I know i will be slower for now but i'm just bracket racing, i think i will still make the class. My 26's i cannot sell as they are down to the cords. That is probably why i got the pin hole last week and i felt like i was skating down the track. They feel like cloth in the middle. I will get some 28's for next year, i'm hoping to get a whole rear end for next season with a spool and at least 4:10 or higher. Thanks

Since you are bracket racing, you might like those 29" slicks. I didn't notice one bit of difference in et between the 28" and 29" tires (I realize that you are going from 26" though), but what I did notice is that my 60' times were more consistent, so in bracket racing, that rules.

You might also want to keep in mind that the tire will 'grow' at high speeds, so you might not think you have a problem now, but you should keep a close eye on it after each run and make sure its not rubbing. I'm sure the last thing you want is a blown slick at 120 mph.

You will need to allow a good 3/4" of clearance for growth around the entire slick. My 28" slicks are the limit without trimming the quarter panel in front of the tire on my car. I can't imagine a camaro having that much more room where the 29" fits.

I'm sorry, but there is no way in hell that a 29.5" slick will fit under a stock fender well. 7.5" b/s? no way. To get mine to fit - mini-tub; cut 3 1/2" front and back of the fender; all bump stops, fenders rolled, etc, etc. UNLESS you jack the *** end up so high that the car looks like some red-neck. If you do it, I want to see a picture. Figure the odd at what rpm you'll be finishing at - may 5000?

They are in there. I backed my LCA'S to move the tires back off the lower inner fender well. I flatened out that area with a small sledge. I had to trim a bit off the back of the wheel well and they are in. Not much room though. You may be right, i might get some rubbing when i use them. I'll see putting it on the trailer tonight. I'll be at the track tomorrow night to see if they will work. If not i'll have to wait a couple of weeks to buy new ones. I just did not want to fall further behind in the points. I've already missed a bunch when i had the transmission out.

Got to thinking about it, and what you COULD do is (but sounds maybe I am too late) is SELL the 29's, and buy a set of 28's....????

Well i ran the car last night with the big fat/tall 29 inch Hoosiers. They barely had clearance and rubbed around the oval stock car track. On the drag strip they did not rub any longer. I only had about 1/4 inch clearance on the backside and i had my LCA'S cranked all the way back. Amazingly i did not loose any ET. My old slicks must have been that bad. I had a 1.60 short time my best ever. I ran about the same ET and MPH 7.33 at 94.5 Mph. The car seemed to like the tires. They were very consistant. I ran a 7.38, 7.37, 7.34, 7.33 for the night. I am still going to replace them as soon as i get the cash but i think i will go with the 28 inch tire now rather than go back to a 26. I think that will be perfect for the car.

Well, I am definitely shocked you did not lose anything (not that I don't believe you, as I do), I am just shocked, as I would have put money on it that you would have. So much for teh "internet" specialist! Haha

OH believe me i was worried about loosing something or a blow out. Like i said i spaced them back with my LCA'S as far as they would go. I bent the back in a bit and it self shaved the rest of the plastic that touched when i ran. I probably won't run them again if i can get the 28's soon. I'm glad i did run them though, it showed me that i will not loose ET by gaining traction i guess if i go to the taller 28 vs 26 that were on the car.
