My partner company has these in stock. They only come in 32 packs though. But I can probably work something out. But you may want to measure the lug hole wheel first.
This lug is
20mm diameter
17mm long on the shank from the washer to the edge
30mm washer diameter
And yes, my keyboard is...
We went to measuring session a while back and they only had Pro's and Trailhunters out. Our 17's fit both so I assume most 17's will be fine. Our's aren't built with any extra clearance in mind.
3rd will fit 4th. 4th wont fit 3rd. The 4th gen has a smaller hub diameter. But they're both 6x5.5 (6x139.7). There are offset differences but aside from looks that won't make a difference when comes to bolting them on.
Even if you were going to use the estimated range you'd have to account for the fact that you're traveling further than the odometer says based on the larger tires having less RPM's per mile.
Unless the new speedo is GPS driven. Then I take everything back lol.
These should help with wheel choices. I'm not 100% sure they're RC but they were the ones that posted them. They look to be similar to the PRO flares, maybe a little wider.
