Currently looking for a perfect sized spacers to install on my P400 X-Dynamic HSE on 275/55 R20 BF Ko2`s.
Recently I`ve been recommended to install 25mm on rear & 20mm on front wheels (in case there are no wheel arches) and if there are aftermarket wheel arches (which makes the truck look wider) then the ideal combination would be 30mm rear & 25mm front.

Any advices/recommendations (preferably with pictures) would be highly appreciated! Thanks

 

Two issues, BFG tread is approx 2/3mm taller than normal AT’s, I fitted 30mm spacers and they rubbed front and rear.

I tried 25mm front and 20mm rear, but the hub studs are 28mm long so 3mm protruded through spacer, and as the alloys had no space at the rear to accommodate this, I had to give up 🤷🏼‍♂️🤦‍♂️

 

Sa.hib, are you mounting these on the stock wheels?

 

Seems like 90% of the market is using H&R, and according to the company`s reps, having considered that the vehicle is 4wd, it is not recommended to use different spacers size, they suppose to be same.

 

No. On 275/55 R20 BF Ko2`s

 

You don't understand the question. You keep talking about the TIRE. I am asking about the WHEEL. That is the round metal thing the tire mounts onto.

 

Sorry, my bad .. )
Indeed, stock/factory 20" alloy - 5 spoke style

 

This tire is 20mm wider than stock. At stock offset (ie with your STOCK WHEELS), that is only 10mm per side (INSIDE and OUTSIDE) of additional tire. You should not need any spacer to make that work. If you are on air suspension, you may have some rubbing in access mode at full lock.

 

To add my experience (which I posted on the "No Lift Tire Guide..." sticky), I installed 25mm H&R spacers on the stock 5098 5 spoke 20" wheels with 275/55R20 Nitto Terra Grapplers. The Nitro's rub ever so slightly at access height, full wheel lock, in reverse. Comparing the pictures of Nitro Terra Grappler's to the KO2s seems to show the KO2 has a more squared transition from sidewall to tread which I assume (possibly wrongly) would cause even more rubbing than the Nitro's. How much? Hard to say.

Also, the wheel studs did not have to be ground when installing 25mm H&R spacers with the 20" 5098 wheel.

That's all I got

 

Did you try them with no spacer first? Everyone assumes that a spacer is always the answer in these scenarios but depending exactly where the rubbing occurs, spacers can exacerbate your problems. Different tires of the 'same' size can have vastly different shoulder profiles and slightly different section width, and I agree that K02s tend to be pretty 'square' at the shoulder.
