When I bought my truck, it had 18" wheels. I bought 16" wheels from a P38 Range Rover. They're the same bolt pattern and offset. No issues.

 

I just replaced my tires. I was so impressed by the performance of the Yokohama Geolander A/T-S that I put a second set on. I got 80k+ miles out of them & they probably would have been good for another 10k if I hadn't bent a tie rod & wore the fronts uneven on a long trip.

My truck is on the road 95% of the time & they handle really well. The Geolanders are awesome in the snow too.

 

Jesssusss 80k miles!?! I would never want a tire with that hard of a compound.

 

I guess the way some people drive rovers causes them to get ridiculous mileage on their tires. I've hear of people getting close to 100k on BFG All Terrains. I've had a set of the Yokohama Geolander A/T-S in the stock size, and I didn't think they were too terribly hard. I didn't put many miles on them though... I took them off and put the much larger BFG Mud Terrain KM2's on instead.

 

Thanks Guys.
Okay my next question - any benefit to running the 16" VS the 18" ? Only problem is I only have 4 - 16" rims so no spare (unless it was an 18") and considering the past few months I definitely need a spare...

 

Use an 18" spare with the same diameter tire and you should be fine until you get the new tire. 16s have a much better ride, cheaper to find tires, can deflate more, and wayyy wider tire selection.

 

I've got about 3000 winter miles on my Grabber AT2's and I think they do a great job in the snow. Not studded (though I'm kicking myself for not doing it when they were new) but they are 235/85r16, so they're skinny and thus dig in pretty well.

I swap my 18's back on during the warm months.
