Rim Upgrade for '83 P'up?

Postby JoeIsuzu » Sat Feb 25, 2017 12:23 pm

It's time for tires again, and I hope to get new paint pretty soon. I'm currently running 15" rims from a Trooper (or Rodeo). I'm considering 16" or even 17" alloy rims. Something used that would adapt, preferably.

Any suggestions?

Jack from recent experience. Offset is most important. Bought a set from new 4 runner 17 inch for my 4x4 project. Pattern, center and lug thread same BUT. Offset put tires in frame at full turn. Mike

That's the sort of info I need to have, thanks.

Keep it coming!

Ok, I've had to do a little more research on "offset" vs. "back spacing". It seems all the rim manufacturers are listing offset now, and back spacing is rarely mentioned. Unfortunately, offset alone won't tell you if it will hit the frame. Actual clearance will depend on offset AND width. The true measurement that determines clearance (with regard to the frame) is back spacing. But no worries, it's easy enough to calculate if you have the width and offset values.

So my next task is to determine how much back spacing I can have without hitting frame...

Jack, the 4" number is legit. I have ran 3 different sets of rims and that is the magic #. You can get away with a different backspacing with a wheel spacer but that is not always a good idea (in my opinion). My truck came with 1/2" spacers all the way around with 31" tires and jacked up torsion bars. I now run 28" tires 215 wide with no spacer and stock ride height with about 4" backspacing. I would recommend not going taller than 28" diameter tires. Some options that I pulled real quick

215/65R17 = 28x8.5R17
215/70R17 = 28.9x8.5R17
225/65R17 = 28.5x8.9R17
215/60R17 = 27.2x8.5R17
225/60R17 = 27.6x8.9R17

Thanks for the input. I'll start looking at 17" rims that have 4" backspacing. :) What's the magic width? I know there's more room in back than in front.

Going for a wider and thinner tire?

Not necessarily wider, and not necessarily thinner. Bigger rims, lower profile tires, but same outside diameter.

Wonder how that would affect handling... Hopefully the roads aren't too bad in your neck of the woods!

It could improve handling, but would possibly make it a little more bumpy.

At this point, I'm still waiting on the painter to call me back. He said he'd have me an estimate within a few days. It's been a few WEEKS now. So rims will need to wait a little longer. I'm not putting new rims on until it's been painted.

Improve handling? It's a fricken 62 hp dsl swayback slug and you still haven't accepted that. New rims/tires might make it look faster and even if you turbo it handling does not even enter into it. I know lipstick on a pig is big down yonder but with that clown paint job it might be overkill. badd Jerry
Powder coating stock wheels with stock tire size is the way to go. Easy on the wallet and eyes.

Jerry,

1. I never said it was for handling, I was just answering Halden's question. Slightly improved handling -- probably. Does it need it? Nah.
2. 62 hp? No, I think the '83 was 58 hp.
3. Clown paint job? Hmm, seems like that should appeal to you. ;)
4. Powder coating the stock wheels would look decent, if I still had them. But I don't care for 14" rims.
