Wheel/Tire combo I haven't seen yet...

Hi all -

Have a 2011 JGC Overland with QL and the 20" Forteras. Thinking of garaging those for the winter, and wanted to ask your opinion on this potential combination:

Goliath Ultra 224 Machined Black
18x9, 5x5in (127mm), +30 offset
http://www.tirebuyer.com/tirebuyerwi...tedItem/138730


Nitto TG's 285/60-18
Rim width 8.0-10.0, 31.3" overall diameter
http://www.tirebuyer.com/tirebuyerwi...0#BVRRWidgetID


Seen some great combos on the site already - including some who put the TG 285/60-18's on with no issues. Question - does anyone see an issue with the +30 offset? (stock being +56). My rudimentary math skills tell me that the tire is +20mm wider, but by pushing the wheel out 26mm (from stock), it should more than compensate... right? The diameter change from stock seems within 3% of stock, which sounds ok.

This is the stock 265/60-18 vs 285/60-18:

Noticed that Webspoke put these tires on Visions warriors with a +25 offset, and seems to be having no issues. Love that look, btw, but looking for a (mostly) black wheel.

Anyone? Not an expert in this stuff, so appreciate all opinions!

Re: Wheel/Tire combo I haven't seen yet...

You really need to find a wheel closer to the 45mm offset and the narrower 265 tire will actually perform better in the snow and slush.

Tirerack has some killer deals on 18" wheels, these are $99 each



They also have most brands (except Nitto) but if you order the package they arrive mounted and balanced, ready to install.

First of all, I really like those wheels you chose. Secondly, a 18x9 +30 should work well. They will stick out about 38 mm (1.5 inches) more than the stock wheels but rubbing should be a non issue 99% of the time.

Might be a stupid question, but how did you arrive at the 38mm (1.5 in)? Bit worried about dirt/mud being thrown down the size of the truck.

Should clarify: Though I will drive these through winter, if all goes well they may stay on year-round. At that point will either sell the 20"s or put them back on when I'm ready to sell the Jeep years from now.

Stock wheels are 8 inches wide +56 offset. Changing to a +30 means you are moving the wheel out 56-30 = 26mm or just over 1 inch. Going from a 8 inch wide wheel to a 9.0 means you add half of that inch width difference which is 0.5inch or 12.7 mm and then you add them up and you have 26+12.7= 38.7mm total width change.

Re: Wheel/Tire combo I haven't seen yet...

Hub bore is 72.6 mm on those wheels and I thought the stock hub bore was 73 mm but I am not 100% sure. Only other possible negative is weight. They are 43 lbs a piece which is heavy. My 18 x 9.5 Vtec raptors are only ~27 lbs a piece (34 lb shipping weight double boxed).

I run 285/60/18 TG's on 18x8.5's with 25mm offset. No real issues with it except some slight rub at park height (which I rarely use), 30mm will tuck them in better, there is plenty of room inboard for this.

My combo:

My combo:


9.0 inch wide with a +30 will stick out about the same a a 8.5" wide wheel with a +25 offset due to the wheel being half an inch wider 0.25" (6.35 mm) gets added to both the backspace and the "front space" of the wheel.

The tire itself will sit 5mm inboard of the pictures, but will have a wider section width on the 9" wheel. It should look great

True that the wheel width (9") won't make the tire itself any wider...

Webspoke - when you say it rubs in park mode, could you be more specific? Only at full-lock? And what does it rub against - shock, nut, or wheel well felt? Apologies if you've already posted this elsewhere...

I didn't notice that... 43lbs is a heavy wheel. They're designed for big trucks, so maybe they're actually steel or a stronger composite.

I went looking around, and found something similar style, lighter and in stock):
EAGLE ALLOY SERIES 079 BLACK


18x8.5, +35 offset, and shipped weight of 34... if anyone has any experience with these, pls let me know.
https://www.tiresbyweb.com/p-7986-ea...ck-wheels.aspx

This site (http://www.rimsntires.com/index.jsp) offers that combination as a package, tho their prices are way expensive. But they do offer a "direct fit" guarantee on the combo of 18x8.5 +35 wheel and the 285/60-18 Nitto TG. To order from them would be $2K vs $1.5K elsewhere, but reassuring to see some validation on the size.

Thanks to the collective genius of this site for the help. Hope this thread benefits others as well.

Actually a wider wheel will make the tire wider. I had 33 x 12.5 17 Baja Claws on my GMC. I had them on 3 different width wheels a 7.5, a 9.0 and a 10.0 The section width was a good 1.75 inches wider on the 10s vs the 7.5s (measured with a tire caliper just for fun) even on the 10s vs the 9s there was a good half an inch width difference. The tread width does not really change but the section width changes. There is a white WK2 on here with 245/75/17 wrangler duratracs on 17 x 9 +20 wheels and they look wider than others running 275/65/18 wrangler duratracs on 18 x 8 wheels.
