Largest Functional Tire Without Mods

[globalgregors]

Fitted today 33” 295/70R17 KM3

Looks great! What do they do to the speedo accuracy @Caveman ?

 

[James]

The rear door has heaps of clearance.

Any rubbing on full lock? Assume you dont know yet about full lock and full articulation?

 

[GrenX]

@globalgregors the speedo is spot on accurate at 100kph.

@James No rubbing plenty of clearance. I dont have a flex ramp to test on full articulation but i have no concern at this point.

Great to hear on both accounts, though I am a bit surprised.

When I have made a similar switch to taller tires (i.e. going from 31.6 to 33 inches in height) the speedometer has been off by ~2 mph at 31 mph (50 kph), and ~4 mph at 62 mph (100 kph). Going up to a 35-inch tire creates even greater inaccuracy, so I've always used a ProCal ("tazer" etc.) to change the tire size in the ECU (back in the day, this wasn't an option, so you just remembered that the speedo was a little slow).

To me, it looks like you are going to get a little rubbing of the tire against the inner fender on-road under a maneuver like taking a 90-degree turn into something that has a steep angle (I have one of these that I regularly drive, and I get rubbing in my Tacoma on 33s even with a 2-inch lift). I hope I am wrong, but that is how it looks based on the amount of room you have in the wheel well. Off road, I would also expect a little rubbing at full articulation. But these are guesses based off my experience with a handful of other vehicles, and I have no experience with the Gren.

Its even harder to speculate about rubbing on suspension components without being under the vehicle.

I hope things continue to go well for you with this tire size, and thanks for posting about your experience so far! I hope you post back if things continue to go well, or if you get a little rubbing, as there are definitely folks on here who are interested. All the best!

It would be nice if Ineos would just release a list of the mods they did to the trucks they sent to SA that were on 35s. Then we can have a definitive answer of how to get there.

Looking at winter tyres, do we think a 285/65R17 will fit ok on the stock17” steels?

Very similar rolling radius according to my sums but obviously 20mm wider

285/70 works, so 285/65 should definitely work as it is shorter in height. With that being said, for a winter tyre, you generally want to go narrower vs. wider (unless you are using it for flotation purposes in powder situations, but then you need much wider)

NOTE CORRECTION!: I'm thinking a "pizza cutter 33" (255/80/17) might be good! You actually get a better contact patch aired down with these tires! Available in Falken Wildpeak!

Yeah, hard finding winter tyres in any size suitable for the grenadier with 17” wheels, 18 no problem.

Maybe I shouldn’t just buy a set of 18’s for winters but then there are the TPMS issues

Not sure what is available in the UK... But here are a few options to look into for dedicated winter tyres:
265/70/17 - Bridgestone Blizzak DM-V2, Blizzak LT; Firestone Winterforce 2 UV, Winterforce LT; Cooper Discoverer Snow Claw; General Arctic; Continental VikingContact7; Nokian Hakkapeliitta LT3

And don't forget to leave articulation room for chains!

Thanks very much , ive not been able to find any of those here

[Baron von Teuchter]

Thanks yes, I saw those

Here are 33" Duratracs (285/70/R17) vs standard KO2s (265/70/R17)

I am considering same tire size. What is your experience with those tire sizes in terms of turning, full articulation, fuel consumption and gearing?

Now that you’ve had these KM3’s a month, have you had any scrubbing issues?
I’m planning to put the same on my truck.
Thanks!

Is there a distinction between tallest and largest? Is there a pizza cutter faction? I'd love a tall skinny 33

@anand loves the pizza cutters!
