Tire size and wheel width change
« on: December 16, 2010, 05:25:45 PM »
The MTs I have are 31" x 10.5R15s.  They are sitting on stock 6" wide steel wheels http://cgi.ebay.com/ebaymotors/SET-FOUR-JEEP-WRANGLER-15-X-6-FIVE-LUG-STEEL-WHEELS-_W0QQcmdZViewItemQQhashZitem483e22118fQQitemZ310280065423QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories#ht_536wt_939 . 

One of the black plastic hubcaps on them busted off the other day and those are cheap enough to replace or remove all around.  But it crossed my mind to look around for a set of used 15" Jeep alloys.  The ones I was looking at are 8" wide and along the lines of these http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=200555463959&ssPageName=STRK:MEWAX:IT#ht_14081wt_1165.  More expensive than I was looking for and me buying them is not exactly certain.  But here's the question:

It's ok to go from 6" to 8" wheel width on the 31" x 10.5R15s, right?  Thx

Yes, it's OK to go from 6" to 8".  Actually 8" will make the tire sit flat on the wheel instead of pinching the sidewalls.  You'll get a more even wear pattern and not get the centers worn out before the outers. The downside is that you don't gain any rim protection when aired down.  If you air down too much you could upset the bead.

The wheel offset is still pretty tight at 5".  Should be fine for the 31's though.  I'd check CL for Rubicons or Canyons.  I forget what those wheels are called. $510 is a lot though.

That's good to hear on the 6-8"

I thought the '03-'06 Rubicons were 16" wheels.  I was checking out some Cherokee mags that looked decent but they were 16" so I wrote them off given my tires' wheel diameter  http://cgi.ebay.com/ebaymotors/00-01-JEEP-CHEROKEE-WHEEL-16X7-ALUM-SILVER-/390270815812?pt=Motors_Car_Truck_Parts_Accessories&hash=item5addf40e44#ht_2388wt_939.

My mistake, you want to keep your tires.  So 15" will have to do.  You might consider 15x7 steel wheels if you want OEM's.  Otherwise you could go with some aftermarket steel wheels for a lot less.

If a set of 4 of the 15x8's hit ebay or CL in the next few months http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=200555463959&ssPageName=STRK:MEWAX:IT#ht_14129wt_1165 and the price with shipping is decent (maybe $400 or less total), I might pick them up.

The ones in the link in my last post might be known as "Ravens" http://collinsbros.stores.yahoo.net/usedrims.html.  Not sure where Jeep came up with that name.

Close, they're "Ravines".

Oh and depending on your area, you may be better off cruising CL or the local paper for a deal on stock wheels... I've picked up two complete 5 wheel sets of stock alloys for $200 each set that way.  To answer your original question, 31x10.5 tires fit like a champ on stock 8" wide alloys.

"Ravines" makes more sense, thanks Dylan.  Those wheels look good on the BFG ATs

Ooo, classic 5-holes.  Those go all the way back to the YJ and XJ.  Haven't seen those in a while.  Probably the best looking wheel of that era.

Is that 5 hole wheel a American Racing Gambler? I like that look too. I also like the look of the MT Classic II.

5-Holes were the Mopar name.  'Gambler' was the ARE name.  The only difference was the center cover.  5-holes had 'Jeep' there.  ARE made both as they still do make all of the aluminum Jeep wheels.
