Pizza Cutters?

I've only got about 1,000 miles on them so far but I'm really happy with them.

Have you placed your QM order yet?

Yes on 4/10, the date the order books opened. Expected delivery in Q4 but you probably know better on the delievery schedule for QM. I heard from Elliot Bay and they said Sept the test vehicles will arrive.
 
They are 255/85R17s. They physically measure 34.5" x 9"
They look very good, have you had to raise the car or do they fit with the original springs, if they are with the original springs have you checked if they rub in any situation, on the other hand have you had to approve the tires or do you not have them there problems with that, here in Spain you cannot exceed 3% of the diameter of the original wheel, if it exceeds it, a technical reform project must be carried out. Greetings Paco

Where do you get this 9"? If one inch is 25,4 mm 255 mm should be quite near of 10" :unsure:

Being strict, the tire size would be:

255/85 R17 is equivalent to 865 mm of total wheel height.
(255x85%x2) + (17 x 2.54) = 865mm

and this in inches:

865mm/2.54 = 34.05 inches
255mm / 2.54 = 10.03 inches

so we would be talking about 34"x10" (34.05 x 10.03)

Correct me if I'm wrong. Greetings Paco
 
Yes. They definitely would have rubbed without it.
Technically, if they fit with the Eibach springs at full compression, then they should fit stock at full compression as the bump stops and shocks are not altered with just the Eibach setup; sure static height is higher, but at full stuff it should be at the same position

Agreed. Assuming that these lifted coils will compress enough to even reach the bump stops .
 
Switched to Wildpeak A/T4W in 255/80/R17 from the factory BFG KO2s this week. So far so good.

Road manners... Improved. Aired up the same as KO2s, the Wildpeaks feel less harsh on poor pavement and easier turning at low speeds. Less noise up to highway speeds, then about the same, just different. I expect good rain and wet snow performance and I'll find out soon.

Dirt manners... Just one long test day so far, but barely airing down (to 31 PSI), they were fantastic in dry, sandy, rocky climbs. Rocky and wet, I expect about the same. And maybe worse in mud, but I have to choose my battles...
 
Installed the 255/85s with no lift. Just driving on road there was no rubbing. Speedo is only off by 1mph. Installing the lift springs now.
Only 1% off? Should be 5+% off, so is the stock speedo/odo off from stock assuming owners will upgrade to taller tires? Bigger question is there any noticeable power loss with larger diameter?

Yes, with GPS the stock configuration is ~3-4% off (low), so the 255/85 brings it back to very close to gps speed.
Have not noticed any power loss whatsoever, and I spend a lot of time in the mountains of Colorado…
 
I run the Mickey Thompson 255/85R17 tires. The speedo deviation increases from confirmed GPS velocity as speed increases . At 30 mph the speedo is ~1mph slow. At 75 mph it is ~3 mph slow. Yes the change in power is noticeable from a gearing perspective. The good low end torque from the turbo mostly makes up for it but my Grenadier was definitely quicker with the OEM tires. I would change the gearing if replacement ring/pinion sets were available. Braking feels unchanged with no material difference in daily driving. I do not track fuel usage so cannot provide any feedback on the impact to fuel economy.

Have you had any issues with the tires now that you e had them a while? Lack of power? Braking issues? Gearing? I have my eye on the same size your running.
