    295-50-15's

    Hi guys, it's been a while. I've been busy with other projects and travel, so the rebuild of my accident-damaged 1988 Unique 427 kept being put on the back burner over and over again. I've finally committed to setting aside the time to get it done - at least most of it before I travel again in June - so parts have been ordered and I've begun work on repairing the the rear suspension.

    I bought and disassembled a complete Series 2 3:31 Powerlock rear assembly and called Alan to get the correct measurements for shortening the axle shafts. When he informed me that 12" is the correct length for bolt-on wheels, I was surprised to find that my old ones, which I had decided not to re-use due to signs of twisting, were too long at 13.5" one side and 13.75" on the other. Because of the excess track, the old 275 60 15's on the back filled up the wells and to avoid rubbing in hard cornering I had the rear height adjusted up more than I would have preferred. I almost ordered a set of 255 60 15 Cooper Cobras so the rears could tuck in a bit more and allow a lower stance, but now that my rear track will be 3.25" narrower overall, I'm thinking of fitting 295 50's instead.

    Any of you running 295's out back, and how do they fit - particularly if you have an older Unique with the narrow-hip rear fenders? Pics would be great if possible.

    EDIT - this is what the 275's looked like on the rear.


    I also plan on switching to a rear braced roll bar - plenty of available options for my right hand driver now that so many manufacturers are making passenger side bars.

    Thanks Phil. Your 295's tuck properly into your wheel wells more than the 275's did on mine. My rubbing problem wasn't on the fender lips, though - the tires only made contact at the inner forward part of the well at the outer ends of the cockpit bulkhead. More of a tire diameter issue I suppose than width. The 295's are 1.5" smaller in diameter which will help and with the new, shorter axles the wider tires won't bulge out of the fenders.

    In that pic the rear end looks lower than it actually is, probably due to the uneven ground.

    I believe mine are Cooper Cobra GT's. Only driven the car twice since installation, but so far they seem ok. Smoother than Avids. It's my understanding Cooper makes Mickey Thompson's 15" tires so I believe they are the same tire and a few $$$ less.

    They are probably pretty much the same then, or close. I"m gonna go with the Coopers, they have to be better than the 15 yr. old BFG's I have on it now.

    Are those TIREGRAFICX tire stickers on your tires?
    I ordered a set of their Cobra stickers for when I order my new tires.
