could i fit 15x10 wheels on the back of my 85 camaro with 325/50r15s? if those wouldnt fit then could i fit 15x8 wheels and like a 275/50r15?

chevyrules85

from reading i dont think the 325s will fit, so will the 275s? also what kind of back spacing should i order on my new rims? 15x8?

good luck man, i been tring to get info on this, all i get is info i 17's LOL, i had 15x8 with 255/60/15 that scrubed the fender, but the back space was wrong, got 245/60/15 on stock wheels now no issure at all, but im going bigger, the only reason i got 245's is they were free, going back to stock on front, here is a link to my post it may help alot, or none at all but worth reading

I have 295/35/19 on the back. They fit fine with only a small amount of the bfh mod. Just one little area that they rubbed. But I also don't have a fender lip. When I painted the car I cut it out and welded the outer and inner skins together. But I don't think it would rub there anyway...I can stick my fingers up there no problem.

325's wouldn't clear. - finding info on 15's is tough as they are really only used for straight line use now days. - If you search for 15" drag tires you'll find specs, including how to fit a 15x10. Drag tires will be spec in inches, but you can check tire manufacturer's websites to compare actual measurements to find what will fit. - several members have ran/run 15x10's and 295/50/15's.
search it out

I have a 92 with Crager's that have a 1/4 offset with 275/65/15's and I can still stick my hand back there and not hang up on anything but it does effect the cars handling, found that out many times lol

ive got 275/50s on mine no problems with clearence. 15x8 welds 4.5 inch backspace. check out my pics. www.cardomain.com/ride/2197664

u used to have 275-60 on a 10" wheel, it streached then out, looked real good

dayton's Z

u can switch between inches and mm by multiplying or deviding by approx. 25.4. for example u want to run a 325/50r15s. take 325/25.4=12.8 inches. soo the tire you want would be approximately 12.8 inches +/- some wiggle room. then ur side wall is 50% or ur width. so to figure height multiply half tire width (the 50 in the tire reading)by 2 and add the rim diameter to figure theoretical height. soo... ((325/25.4)*.5)*2+(15in)=27.8in. tall.

for 245/60R15 ((245/25.4)*.6)*2+15=26.57 in tall.

hope that helps to convert metric tires into inches and vice versa for drag tires in inches.

Yeah That was me and I still don't have a answer.

From what I see a 10 wide is the biggest for wheels. Drag wheels in mind here without looking bad and 5.5bs is the golden number. As far as what realy matters the tread size. I still have no idea.

FACT is so many people on TGO don't understand all these tire sizes. Gives me a idea.

lol never had a 10 inch wheel if i wrote that sorry. but i did have my buddies 275/60/15's on until my mickeys came in. mickey thompsons are hard to come by right now. mine are 275/50s

stiletto

just saying the combo that i had on my car. hell with then radials. slicks all the way.

BNBZ28

iTrader: (1)

stilleto i think ive seen your car out at bithlo. you go out there much? and yea i think i regret going from slicks to radials. im gonna try and go on friday maybe i will hook. just got some umi parts in.

stiletto

yeah, the radials are too undepandable, unless track is good. with the slick the car will 60ft 1.37 every pass. 1.40 is the worst it's had. im looking for 1.30's just a little more spray and i should do it.
i have a 28x10.5 on a 10" wheels.

chevyrules85

so if i run a 15x8 wheel with 4in of back spacing, i should have no problem running 275/50r15's? would that back spacing be correct for my car? also what is the bolt patter on our cars? would this be correct?------> http://www.jegs.com/webapp/wcs/store...10002_50690_-1

stiletto

when i first got my car 8 years ago i had 15x8 and a 275-50-15 . they will work

BNBZ28

iTrader: (1)

you want it to have a neutral backspace. so on a 15x8 you want 4.5 inch backspace. bolt pattern is 5 by 4 3/4

chevyrules85

so what bolt pattern and back spacing will work for me?

made it out last night. take back what i said about the radials, pulled the left front tire about 2 inchs on a 1.63 60ft. with a new best of 11.16@124.8. a few more tweaks it will be in the 10s. and i drove it to and from with the ac on.

stiletto

not bad, randy must have prepped the track, the air was decent last night.

BNBZ28

iTrader: (1)

track was good for my first pass, but as usual it gets worse as the night goes. 2nd pass was 11.35@124 spun real bad. im gonna go next week to try for a 10.9 pass.

stiletto

yep thats how it is , i only make 1 or 2 passes. and i go home.

BNBZ28

iTrader: (1)

i make as many as possible. only got 2 last night. would have gotten 3 but i didnt make it out there until around 7:30. it was a last minute idea, "hey lets go to the track" needed to try out the new suspension anyway.

stiletto

honestly go to bradenton on a saturday and do there test session from 9-3. its the best testing you will ever do. i love going down there. track always works, shut down has a slight up hill grade dont have to use the brakes much to slow down. i went down there and did 10-12 passes with adjustments and tuning in between

BNBZ28

iTrader: (1)

nice i want to do that but its a 3 hour drive for me and gainsville is about 2. bithlo is only about 45 minutes. ive been told to go to bithlo on a bracket night. track is always preped.

stiletto

bradenton is a 2 hr drive for me. i hate bracket racing , buti do do it the is good on them nights, but if is cool and the dew settles it goes away real fast. Gainesville is a total piece of crap for a track!!!!!! everyone thinks they have funny cars go down it that it is the best. Only good for the gator nationals.

iTrader: (1)

yea im thinking about going on a bracket night. im guaranted 3 passes and the track is prepped. maybe next weekend.

stiletto

just start bracket racing its fun the more and more i go it grows on me, this year im going togo to st.pete and racing the heads up madness events.

yea as soon as i get a trans that will last. i put this tci reverse manual valve body in since then i have cooked 4 trans. it works for a few passes and then starts to flare into second gear.im gonna try and send it back and get something else.

stiletto

seriously get a 400 trans, you will never have to getanother tranny again! thats what i have in my car. it has a tras brake and as soon as i let off the trans brake button the nitrous come on so more less i leave on the nitrous.

i would do that in a heartbeat, but i drive it on the road still with alot of highway cruising. not ready to give up overdrive yet. also ive got lockup so im locking the converter in 2nd gear at the track. keeps the rpms down and it mph's like a ****.gets the et down as well. there are people running in the 9s with this trans, i should be able to go in the 10s with one.

stiletto

i have a 400 witha 8" converter and i have been driving it every where around orlando lately. down i 4 and everything

yea but whats your rpm at 80? im turning 2600. ran again tonight trans worked great i guess it just doesnt work on the street, but thats fine with me. 11.006@125.45.

no speedomete in the car, i dont know
