well, anyone running a 10" wide wheel on the back? i don't want any tire to protrude from the top of my fender line. i plan on running a cragar street star wheel with a M/T ST/ET tire and i would like to know what the largest i could go with the tires before mini tubbing (or anything extensive for that matter). what about backspacing? anyone got pics of 10" wheels?

 

Depends on the size of the tire

I use 15 x 10 rims with 5.5" backspace. When I had tiny MT ET street 26 x 10.5 I had no problems with clearance and they fit under the fenders. I switched to MT ET drag 28 x 9 slicks and still had room. Now that I use Hoosier 29 x 9 slicks, I had to modify the fenders a bit. My tire size limit without doing some major fender work is the Hoosier 29 x 10 slicks.

 

Here's a shot you'll understand, this pic with 15 x 10" Weld Draglites 5.5" bs, 26 x 9.5 Hoosier Quik Time Pro, stepping upto 27 x 11.5 by this weekend.

hey IHI,
can i see a pic of your car from bumper level? Like take the camera about 2 feet off the ground and shoot a pic?

I would really like to see how those slicks look from behind at an angle like that.

 

it's been raining, all weekend, and I gotta work outtta town this week, but I'll get ya a pic as soon as I can. I got this one here, but the shadows kinda screw up the stuff.

 

Hey IHI since u said ur stepping up on to a bigger tire. how much would u want for those slicks? just the slicks. becuz i hope to order a set of draglites new the end of May or earliyer (sp) and if u have no rubbin issues with those and u have 15x10 rims with those tires. i think ill go the same route. also if u will sell those how many passes do u have on those slicks? or if u want to PM me about this cool.

 

slicks had the all last season on them-DOT slick and the grooves are gone, but there is still alot of rubber according to the dots in the tire. I got a neighbor down the street that's been hounding the crap outta me for them when I take them off, so they're spoken for-sorry. Told him $20 since Iwas just gonna trash'em anyhow.

 

ahh okay then. thanx man.

edit: what is the bolt patteren size for our cars? becuz im lookin at the draglites on Jegs and i dont know what the bolt patteren size is.

edit again: im lookin at the hoosier slicks and well they dont have 26x9.5x15's they have 26x9.0 and 26x10.0 by 15in and i was woundering will there be any issues running the 26x9.0's on the 10in rim? or will there be any rubbing issues with the 26x10.0?

im looking now they have 28x9.0x15 slicks that will fit on a 9-10'' wide rim. would that be better? i have 255/60/15 rear tires and i have a 3.23 open rear. before i use these at the track i plan on gettin a posi installed and probably 3.73 gears if i can afford it at the same time.

sorry about all the questions i just want to make 100% sure on everything before i order it and something is wrong thanx guys

 

GM small bolt pattern is 5 x 5 3/4". Most GM cars including all F-bodies.
GM large bolt pattern is 5 x 5". Older full size cars and all the late model trucks that use 5 bolt.

Ford cars is 5 x 4 1/2"

Some rims such as Weld Drag Lites use a dual bolt pattern. They fit Ford and small GM on the same rim.

 

so our bolt patter size is 5x5 3/4? okay kool thats all i really needed becuz i wasnt sure what size it was.

 

BIG time type-O ours are 4 3/4" bolt pattern. 9" slicks on a 10" rim looks funny, get at least a 10" wide so the side walls are at least straight up and down so it'll look better and the tire will work better, just be sure to have them put on bead glue when they install the slick on the rim, last year I kept spinning the rim in the tire until I found out about that trick. There will be no rubbing issues with a 10" slick, 11.5 from what I've gathered I'll have to do a little banging on the front side on the rear wheel well-but that's fine by me-it'll look "cool"

 

okay so its 4 3/4 bolt patteren. and okay ill get a 10'' slick. Also is that bead glue called something else like "bead sealer"? becuz if so then i hope to get these slicks and rims while im still working at pepboys so i can put them together myself and not worry about some idiot puttin them together and trying to balence them.

 

I'm not a tire expert so it might be the same stuff, some guys said just run a bead of RTV around the bead before you seat it, I do alot of business with a local trucking tire company so they have some heavy duty stuff, they just called it bead glue-buddy had his slicks mounted/balanced at a different shop and when he asked for the slick to get glued they knew right what he was talking about. So it's probably same stuff just different names depending where ya go. I think you'll be happy with the look of the 10"rim with 10" slick.

 

ok whenever you can get that pic for me would be great.

 

I'm no professional photographer, but seems the shadow will always be there, I took a couple early this morning with the sun at my back and you could'nt see anything, took these around lunch time, about the best I can get, but the rim size/bs/tire size will fit no problem.

 

works for me....thanks for the shot. I appreciate it.

 

My typo error but it was caught. Yes 5 x 4 3/4 is small chev.

I currently use a 9" slick on a 10" rim. When I burn these ones off at the end of the year, I'm putting on Hoosier 29 x 10. They'll fit but I'll have to do a little bit more modifying to the front of the inner fenders with a hammer. I get tire growth so even though they look like they have lots of room sitting still, the tires grow enough to rub on the fenders. A 26" tall slick will have no problems. It's just those 29" tall tires limit how wide they can be because of how the inner fenders are shaped.

 

I just bought some weld wheels 15x10 with 5.5 backspacing.now before i mount slicks on it (26x10, if i do mount the slick i cant exchange the rim) ,i just got to make sure it fits well with no rubbing.i jacked the rearend up and found the rim being about flush with the fender(quarterpanel),will this be ok it might stick out a tad i think.I also have the 9bolt austrailian rearend with disc brakes, it looks like im going to have to grind the calipers a little for fit issues.

Ya 29" is a big tire for our cars-near some steep gearing too, but it'll look bad -*** when she mounted, kinda the reason I'm stepping up to 27 x 11.5, more for the look than a necessity, hell I hook just fine with the 9.5, but the 11.5 will give the "mini-tub" illusion, and hopefully next season it'll warrant the extra meat

Are the calipers on the 9" GM rears bigger than standard calipers, mine fit just fine with my rear discs? standard 10bolt though.

 

yes 9 bolt verision caliper is a tad bigger.it hits the inside corner of the rim.looks like im going to have to grind away.is there anybody else out there that has the same problem as me.

 

The GM 9 bolt calipers are the same as the 10 bolt.

They key to proper tire sizing is to stuff the biggest tire that will fit inside the wheel wells THEN select the gear ratio to best suit the tires. My 29" tires work well with 4.56 gears at the altitude I race at however if I go to any track at a lower elevation, I need to swap out the center section of the 9" for another with 4.30 gears. If I don't I'll run out of track before running out of rpm. I found that out last year when I went to Yakima. I was at the engine's red line just before the 1000 foot mark. I floated the valves trying to reach the finish line.

I'm only shifting at 6700 rpm. If I had a SBC screaming to 7200 rpm, I would probably need something like 5.13 gears.

Don't forget that DOT tires and slicks are measured differently. The width of a slick is across the tread. The width of a DOT rated tire is across the section. This means a 10" DOT tire might only have 8" of tread on the ground. On the other hand a 9" slick might be 11" wide across the section.

MT, Hoosier and Good Year all have their tire specifications online so you can check the true dimensions. I had MT ET drag 28 x 9 for a while. Although they call them 28" tall tires, they're actually only 27.3" tall. When I needed new slicks I needed a 29" tall tire. MT doesn't make the size I needed so I went with Hoosiers. After I bought and mounted the 29 x 9's I did some remeasuring and found that 29 x 10 will fit so that's the next size I get. If I could find some way to squeeze a 30" tall tire inside the fenders, I would.
