I'll keep the format the same.
I decided to go with 215/80R15C Firestone Destination A/Ts
Here is my experience so far:
Power loss: Quite severe. I find pull off harder, and I change down a lot more often. Not able to keep the same speeds on the uphills as I used to with stock tyres.
Look: They're black
Ground clearance: 30mm extra. Clearance is now 220mm
Directional Stability: Compromised a bit. It might be both a combination of AT tyres and higher profile. Then again, the ride is now softer and quieter.
Speedo readings: 5km over true GPS speed. At about 115 on the clock I am doing 120km/h on the GPS (This also contributes to what is sensed as power loss on the open road).
Fuel consumption: I haven't noticed much difference. My highway commute, I do 8.4l/100km. If I push it, I end up doing over 10l/100km where I used to do 9.5 l/100km. I adjust my calculation by 8% to compensate for the difference in tyre size.
Tyre rubbing: Lots. They touched the bumper when the wheels were turned, but a quick pull on the front bumper increased that, and trimming the little tabs at the bottom edge of the bumper. They rub on the rear of the front arches. They rub the rear arches. Especially over large speed-bumps (which I usually take too fast) and at full articulation.
Pressures: Not really sure. My gauge doesn't seem to be accurate. Currently running 2bar (according to the garage's gauge) for highway use.
On-road: A lot quieter than stock. Better wet road performance. Appear to have better cornering traction too.
Off-road: Increased diameter, doesn't appear to affect off-road power. 3cm clearance is useful, appear to have decent off-road traction. I was able to get further up a steep loose slope than another Jimny with 215/75R15 BFG A/T's.
Happy chappy?: Yes, considering that they rub, and rob power, the extra clearance and off-road traction are worth it for me. I can't recommend this upgrade.
Price: Got them for just over R1000.00 a piece at Supa Quick Ruimsig.
Previous tyres: Bridgestone Dueler H/T 207/70R15 (Stock). 55000km before I replaced them. They were worn down unevenly. Reasonable on-road. Poor performance in slippery conditions.
