I made a trip a few weeks ago to Ouray and was able to explore a few trails. Nothing major, but I managed to cut the sidewall on my GY Wrangler Adventures. To be clear, the cut did not go all the way through and I was unaware of the damage until today. There was a rubber flap that exposed all the way down to the belting …. I feel very fortunate not to have experienced a blow out on the highway. I dropped by the local Discount Tire, and they fitted a new set of 275/55r20 KO2s. Travis was very helpful and said they’d had very good luck with that tire and size in the Defender. So, an hour later … new shoes all around.

 

I am so close to going the same way. What tire pressures are you using? The standard as per regular load? What changes do you notice to the ride and feel of the handling?

 

I just put the tires in yesterday and these are my first set of KO2 - so no real experiences yet. I spent most of last night trying to figure out what pressures to run for “light load”. I found the load progression chart for the KO2, but couldn’t find one for GY Adventures - so, right now I’m running them at the “max” inflation of 65psi - which is really high - but is where the two tires “intersect” on the charts. I’ve talked myself into somewhere between 50 and 55, but I’d feel a whole lot better if someone with more experience could recommend a specific pressure for these tires on our vehicles. If I could find the load progression for the GY tires, I could match the light load recommendation from the vehicle manual to the load values at those pressures for the KO2 - and then there wouldn’t be any mystery. Maybe someone has that pressure / load chart for the GY and will post it!

 

Yes, I see no specs for the stock tire size. Funny but what you pulled shows max tire pressure at 50 and normal loan recommended is 52 rear if I remember correctly. I have been running the light load pressures when only me driving and on a recent loaded trip to Oregon still used about 4lbs lower than recommended on normal load - tire pressure went up so high when warmed up it was freaking me out. 49 on rears went up to 57 or so. Why don't you strat with the LR recommended? Are the specs for the two tires are that different?

 

The way I understand it is that the JLR recommended pressures are specific to the OEM tire - so, you have to look for load / psi equivalencies for any replacement tire. I’m probably over thinking it, but I was just trying to get to something that would map from one tire load / pressure to the other tire load / pressure. I do t worry to much about “hot” pressures since the manufacturer numbers are all given as “cold” values … I expect they plan for the pressure rise when the tires heat up and take that into account.

 

I just made a trip to Ouray - its a great place - I started in Santa Fe - Red River - Durango - Silverton - Ouray - Breckenridge - Denver - Santa Fe

Great country

Tire pressure should equate to the vehicle recommended tire pressure if the tire is a replacement fit regardless of mfg / tread design. - a change in size would have an impact

 

That’s an awesome trip! We live near Castle Rock - so not a long drive for us. I hope to go back in the Fall. We did a couple of trails between Ouray and Telluride. None of the technical stuff - mostly gravel and mud with pretty strep grades. The most technical thing we did was drive all the way to the end of Yankee Boy - that’s where I suspect we sliced the tire :-(. Absolutely stunning drive though :-).

 

I have a MY22 Defender 110 and have the OEM off-road Wrangler Adventure All-Terrain tires. If I'm reading the specs right, the 275/55 R20 BFG KO2s weigh about 15 pounds more per tire (than the OEM Goodyears). Is mileage OK? Any other drivability differences?

We have BFG KO2s (315/70 R17, basically 35-in) tires on our Jeep Wrangler, so I like the tires. The 35s are a bit bigger than the stock 33 KO2s on the Jeep, and I definitely see a difference in MPG. These are totally different cars (and the Defender's got a lot more power than the Jeep), but I'm curious. I'd like to lose the stock tires if I can.

Thanks!

 

I had KO2s in that size (same size and tire as a Raptor comes with, incidentally) on my 14 Wrangler; I wasn't a fan. Kept them on about 8000 miles then sold and replaced with a narrower 35, the 35x10.5 Kenda Klever RT. Skinnier, a little taller, quieter and seemed to track better on the highway.

I'd give a dollar to be able to fit those skinny 35s on the Defender.

 

love the skinny "jeans" look - never thought I'd say that :-)
