17x7.5 Rim... will 235/80 be too narrow?
 
I just got my JKS last week, and I feel the need to get decent tires. I also want the Pizza Cutter look. I got the old style rubi wheels (5 spoke), 17X7.5. I was looking at the duratracs and 255/75R17 would be perfect, however they don't come in that size. My two options are:
  • 235/80R17: 31.8 inches tall, 9.3 inches wide, the look I'm looking for.
  • 245/75/17: A bit wider and a bit shorter, not a big difference I guess but more expensive.

I want to go with the 235's, but I'm concerned about the tire being too narrow for the rim. According to GY, that tire can fit 6 - 7.5" rims, with the ideal being 6.5.
The 245 can fit 6.5 - 7.5 with the ideal being 7.
So 235 shouldn't be a problem, but would like to know from more experienced people.

Thanks a lot!

BFG km2 in 255/80-17 is definetly a pizza cutter. Looks good on stock rims.

Sure, that was exactly my choice but I need something a bit safer on packed show/ice. I'm not concerned about getting stuck as I'm concerned about not being able to stop.
Those BFG may be my Summer tires.

Did you ever figure this out? I've been kicking around the idea of sizing down a bit from the Rubicon stock KM mudders to a dedicated winter tire (Blizzaks, Winterforce?). The 235/80 seems like a logical choice as pizza cutters are known to work in the snow, and going down a slight amount couldn't do much but help in the case that you do get out of control.

If you're worried about winter performance, have the tires siped. Most tire centers can do it and it's not expensive. You can turn an aggressive M/T into a halfway decent snow tire.

LONG POST WARNING:

I've tried tire shop siping on the original KMs a few years back. Didn't get any result in icy driving, but the tires did chunk out A LOT faster and I only got about 25k good miles before I had to get a new set.

Since then I've tried actual snow tires and the siping is great, but the real impact is the low temperature softness of the rubber compound. I've been driving CO winters for 16 years, back and forth from Denver to Summit County and I'll tell you from direct experience nothing, NOTHING, compares to a dedicated snow tire in an emergency stop or avoidance maneuver.

I'm admittedly an old man driver and am cautious to a fault, but other drivers are not and I've been saved at least three times over 5 years from catastrophic accidents thanks to my dedicated snow tires.

Now from a cost/benefit standpoint some might not consider 2 sets of snows over 5 years worth the opportunity cost of other Jeep mods. But when the rubber meets the road (pun intended) i want my money invested in two sets of tires, one for the off road adventures of summer and one for the nightmare of driving with idiots in their Mustang on i70 in a blizzard.
