So I am about to pull the trigger on a much needed new set of tires for my 78 lwb/ 1/2 ton. Currently it has what I believe to be factory ralleys...15 X8 and 15X7's...I am going with 295's on the rear and can not make up my mind whether to go with 255/60's or 265/50's up front. I don't want the front end riding high....but I also don't want too short of a sidewall...I would prefer a complimentary size to the 295's...I read elsewhere that the 265's shorter sidewall looked funny....
Any thoughts?
My ride is here......

If you're using your 15x8 and 15x7 rims you're pushing the max width limitations on both. Some tire places will have concerns putting them on. The 295 50's on the back are only 26.7" tall and will affect your rear end ratio and speedometer. I would suggest you consider 275 60's on the back with a closer to stock height of 28" and they would fit on the 8" rims nicely (I have them on front and back). If you want something smaller up front, I would suggest 255 60's up front. They're almost and inch narrower and an inch shorter than the 275's. You're truck looks lowered, so you also have to consider the looks and how much wheel well you want to fill. The lower the profile tires, the more open space on top of them. Its personal preference, but I think 60 profile tires look better in the 15" size.
Note: my speedometer is off about 3 mph with the 275's on the back.

Hi Scott,
Yeah...thanks for the information and reply. I knew the ratio/speedometer would be off. I bought the truck lowered...quite a bit actually.
I ended up going with the 295/265 combo and I am happy for now.
