Too much inward offset and the wheel rubs on the tie rods in front.
Too much outward offset and the tire rubs on the wheel well in back. I did the roll the baseball bat thing on mine and it worked well, although I didn't have pait to worry about.
I personally wouldn't go any wider than 7" wheels and wonder if 6" isn't enough for tires up to 205. Everyone seems to want really wide tires these days and I'm not sure why.
I agree that if investing, 14" should be skipped. 70 series 15" will probably get you in the 80 series 14" diameter.

For a 14" x 7 "wheel what tire would I go with , maybe 195/75R14?Tires are limited but Hankook has a whitewall to go with a Supreme mag

How about a 15" x 7" wheel maybe 195/70R14?

I'd go with the 15" Tires should be fine.

Jack, last post was September. Was wondering what you decided on, if anything. Like others, I am wondering why you keep going back the the 14" diameter. I am in the process of deciding what to do with my 61 Rampside. After reading all the other comments, and knowing that a friend of mine has 16" wheels on his Rampside, I have decided to go that route.

Summit Racing has a great selection of wheels and a wizard that makes it super easy to find the wheel you want/need. If you look for a 16"X7" with a 4" backside, you will find over 40 options. With a 16" wheel, you could use a 205/70R/16 tire and end up with a 27.3" overall diameter which is perfect for a Rampside.

Just a suggestion.

I went with a 15" x 6" Cragar chrome Smoothie wheel and Michelin Defender 205/15R65 tire.

Thought I'd drag this up to the top and see if I can get some more specs and details on potential wheels/tires for my Loadside. Cliff says 16x7 with 4" BS and 205/70R-16 tires. Jack went with 15x5 (unknown backspace) and 205/65-15 tires.

Any others?

I can't spend much more than $200 per wheel/tire combo.

You should match the tire width to the rim width. 205s are the right size for a 6" rim. You obviously can go wider. I wouldn't go narrower than 6".
I've got 16x8s with 245/45 but that would go over your budget.
You can pick up '82-'92 15x7 Z-28 wheels for about $80 used. They fit fine on the back but you would need spacers on the front. There are a lot of spacers on eBay cheap.

Lane 66- Ouch! On brief inspection it looks like these fit and I'd expect the top to move inward on suspension travel. How much clearance was there from the tire to wheel well edge, straight up and down? Is that tear from flexing the panel or was there fiberglass on it?

Do we have to pull the springs to truly test or is weight in the truck, tire on a jack close enough?
Need new tires on some wheels I'm planning to use and don't want to go too wide. Not sure of the backspace on these wheels.

You are correct. The FC rears swing in plenty so if they don't touch the fender at rest and the camber is close to zero then they will pull away as the suspension compresses. I have 8" wide IROC wheels on the back of my '63 GB with 245/50 tires and the only place they rub is a little on the e-brake cables. I did have to do a little grinding where the wheel was closest to the control arm and on the shock tower where the wheel was closest.

Thanks, Dean. I guess 4 1/4" backspace on those beauties is a good fit up front because of the tall inside diameter of a 17" wheel means the tie rods miss the edge of the rim? Right? I like 'em but can't afford something that nice right now.

Dean, can I ask what the ride is like with those 17's on please?

Does it handle better, worse or no difference? And does it feel any less bouncy?

Ta in advance.

I decided on US Wheels Smoothies. 15x6 with 3.75" backspace. For tires, I went with BF Goodrich Advantage TA in size 205/65-15. I got the raw wheels from Summit and painted them "rattle can red". I just put them on today and took a 20 mile test drive. No rubbing at all.
