Need a tire size suggestion.

So the front tires on my 66 are currently 235/60/15, on mickey thomspon 15x8 wheels. That was what the po put on....my question is, what would you recommend switching to? The 235/60/15 is a little wide for the front, although it does fit just fine, I'm not sure if that much width is needed. The other issue is the cost of the tires, while not the most expensive, they seem to be a much less common size tire on 15. Any suggestions?

Fwiw, this is the front tires ONLY, so don't worry about the speedo being off...since this thing has always had different wheels and tires on it, I have no idea if the size is what it "should" be.

Re: Need a tire size suggestion.

Is the truck lowered? If it's stock I've seen a 31" tire on the front. That tire is real small fora full size truck, have the same size on the front of my car. Maybe a 235/70?

Do you plan to utilize the current 8" wheel? If so the 235mm width is the minimum I'd do. Swapping to a narrower 7" wheel you could do a 215 or 225mm width tire in a 70 series or even taller 75 series height.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.

Re: Need a tire size suggestion.

Any size tire will fit on an 8" wheel. I had an 87 that had the factory 8s and had 225/75s on it. They fit, but didn't look the greatest.

I saw after the fact that the truck is lowered. If you want to keep a fat tire (which a lowered truck should have IMO) a 255 or 275/60 would look good I think. If not, then the 235 I mentioned earlier or a 255 would work too.

Agreed.... Any size can 'fit'.

I just don't recommend a narrower tire on an 8" wheel because it looks stretched vs what's typically utilized on the rear. I'm fine w/a 225/75 on an 8" wheel if a 275/60 is used on a 10" wheel as it keeps the sidewall proportions (stretch) symmetrical.

225's on an 8" wheel in front & 275's (or greater) on an 8" wheel in the back is a no-go for me.

Re: Need a tire size suggestion.

The truck is roughly 4" dropped in the front, and I DO plan to keep the 8" wide wheel. The tire looks fine in the wheel well, maybe a little small but not much. I'll take a look at some "bigger" tires, i just don't want to run my inner fender well at all.

Scoti, did you mean a 255/60 or a 255/75?

255-60 would be slightly taller vs the 235-60 but a tad wider as well.
I've never heard of a 255-75 series tire in a 15" diameter.

If you want a narrower front tire that offers a bit more height, the 225-70 is a good size (235-60 = 26.1" OD; 225-70 = 27.4" OD).

I'm running a 245-60 on a 15x9" rim on the front of my Silverado with a 4" drop on the front

Re: Need a tire size suggestion.

I've found both 235/70 and 225/70's for the same price, both rated for light trucks (not really sure about running pass car tires on this thing w/ a v8)

I'd say those are prob my best bet for the price and availability, as well as the rating right now.

No different than a pass car of similar size w/a V8. Where it matters is when the vehicle has or pulls extra weight around.

Re: Need a tire size suggestion.

I honestly didn't know that. I always thought there was a "reason" but I guess if my drag radials hold up fine with a load in the bed (long story), then a car tire would be fine up front haha.
