Tyre Question

[JMF]

Does anyone know if 255/60/15 tyres would go on a 15 x 10 wheel ok ? Also would that combination fit ok under the rear of a 68 ? See link for the wheels i'm thinking of getting, as far as I know my car is stock height, see pictures below, i'm wanting to use my current tyres, I think the rear wheels are 15 x 8 at the moment, thanks

255 is way small for a 10" rim..(IMHO) 295 will fit real nice. Heres mine: (5" bs)

p.s. please cut your exhaust.

I see the same thing about 255 and 10 inch rims as the others. 

I am mostly writing to say that I like your car  - even with the blacked out bumpers - which is not what I am used to. 

I also agree with the comments about the exhaust.  If it were me, I would switch to exhaust tips.

your car is sick!! I've fit 205/50/15 on a 9 and 10" rim, so yes they'll fit. Thats what I currently have on my ae86 drift car..

205/50/15 on a 15x9:

Gotta admit I don't know the logic behind the drifters using narrower tires on wider rims unless it is just to make them easier to spin and slide.

In general, you want a rim that is +/- an inch of the tread width. While you can make others fit, it isn't ideal, like a 295 on a 7" rim or a 205 on a 9" rim.

I would think a narrow tire on a wide rim would make for a very stiff sidewall. You see it on "jumping" cars, and low riders with hydraulics.

I personally like the look of a tire that is around 1" wider than the wheel it is mounted to. Just looks right. A 255 mm width tire is 10" wide, would be perfect on a 9" wheel. Looks better on an 8" wheel than a 10" wheel, just my preference.

biggest reason for streching the tires is to reduce the sidewall flex, which is not what you want as a drifter. Also a lot of drifters run cheap tires and streching the tires to stiffen the sidewalls is cheaper than ponying up the cash for the good tires. Some also do it for the looks. Also some guys are obssesed with lower ride heights and huge negative camber (or demon camber as its called) which don't go nicely with taller profile tires

[HPP]

I think this may fall into the voodoo realm as stretching the sidewall doesn't dimensionally change it and putting it on a wider rims just turns those two sidewall plys from vertical  to an oblique and allows side loads to roll over on the sidewall instead of the tread face. Of course, all the extra psi you need to put in it  to keep the sidewalls from collapsing may be the true benefit of it. I'd think it would make the tire actually softer, at a comparable psi, to a more vertically oriented sidewall. Now it will reduce its overall height slightly.

I think low riders do it because of the origin of the species. Short on cash immigrant workers who developed the low riders bought the cheapest tires they could, which were smaller than they were supposed to be for the rims they were running, which created the "may pop" look common on low riders.

Think i'm now decided on what wheels I want, do you think this combination would work on my car with this backspace? If I understand it correct that backspace will push the wheels out more towards the arches? Thanks

Rear - 15 x 8 - 255/60/15 - 3 3/4" backspace
Front - 15 x 7 - 225/60/15 - 3 3/4 backspace

The wheels on there at the moment are 15 x 7's all round with the same tyres as above

See 1st post for pictures

Anyone know what backspace those wheels I have on it at the moment are ? Not sure what make they are but they are the General Lee type wheels

[XH29N0G]

Make sure that backspace works and/or gives the look you want.  Someone on here will know.  My impression is that 3.75 inch backspace is a little less than what I am running which I think is 4.5 on a 15/7 and a little more on a 15/8.

[Patronus]

Pull off a wheel and turn it around to the back. Lay a straight edge across the lip and measure down to the stud flange. Viola', your back spacing.

[JMF]

Just remembered I had the same wheels on my old 68 with 275/60/15 tyres at the rear so i'm guessing i'll be ok ?

[XH29N0G]

Would seem so.  That looks good.

[polywideblock]

why not just fit 275/60 TA's   to the 15x8 rear rims bigger foot print means better traction   

[JMF]

Will 295/60/15 go on a 15 x 8 wheel ok ?

[JMF]

295/50/15 rather

[HPP]

Yes, but you will need to run it at less than 32-35 psi to get a full foot print or risk wearing out the center tread. Lower pressures tend to run hotter. Hotter temps mean higher risk for problems.
