2" difference is huge.

 

BFG does not make a size for the 18" rim similar to my 20" size.

My set up is a 295/70R18 with a 3.5" lift the Fuel rims are a +20 offset which is pretty close to stock. Couldn't do much more without rubbing on the fender tires are Cooper STT Pros and measure about 34.5"× 12"

That's correct. I look online and couldn't find an equivalent size but they do make a 34/12.50R18 and a 35/12.50R18 but I worry with the width they'll rub.

 

My set up is pretty much the same as yours except a add-a-leaf and helper spring in the rear vice your airbags.

 

How much clearance do you have with your set up? Based on yours do you think a 12.50 width will fit and not rub or is it gonna put me over?

BFG may not, but there are plenty of 295/70R18s out there which is very similar in size. And they will rub with just a level, just like his does with his 20s.

285/65r20. 2" RC level up front. 2" firestone airbag lift in rear.

Im think about doing the same tire set up with my truck. Do these rub any?

 

thanks.

No rub, see below how to fix.

No rubbing if you do this to pull back the inner fenders:

Here's how much clearance this gave me at full lock:

Curious how how these would wear on my 2500hd 6.0? Anyone running these on the HDs?

I am running LT 275/70R18 KO2's on my 2015 2500 HD 6.0. I love 'em. I live rural and deal with several miles of gravel road any time I leave the house. They do a great job when the gravel road is a muddy mess. They do a fantastic job for work on the property. Fantastic for snow plowing also. They ride great and are pretty quiet on the highway. Had them on for a year now and they look almost brand new. I didn't lift the pickup. I lowered the back a couple of inches using McGaughy's drop shackles so the pickup didn't look so much like a cat in heat and put on a set of Sumosprings on the back for some support. The Sumo's give a ride almost like I have air bags under the back.

 

I got the load / pressure chart from BFG on these tires and inflate them more in line to that recommendation based on the load on the tires at the time. I only inflate up to OEM recommended pressures if I am really going to be loading up the 2500 close to max gross. Most of the time, when empty, I am running 55 up front and 50 in back. Great ride, good even wear.

How did you get that? On the website or have to contact them?

I contacted BFG thru their website and asked for it. Now you have play a little coy in doing so. Never tell a tire maker what vehicle you have the tires on, only the tire type and size. If you tell them the vehicle, they just punt back to the OEM. If you state only tire type and size, they will give you the load pressure chart for that tire. That is how I got it.

 

On commercial tires, we use load pressure charts religiously to maximize tire life and performance. I take that same mindset and do thus with my pickup tires. The tire maker is the one who made the tire. They put in all the R&D and they know how the tire should be used. The vehicle OEM recommended pressures are for max gross loading of the vehicle, and for that, they would be right. But the 2500, at least mine, there is 2300 lb difference between empty weight and GVRW.

Makes sense, when going to a total different wheel and tire size I would think the OEM go out the window too. Going from a stock 20 to a 17 with 33 cant imagine OEM air pressure would be right.

Changing wheel sizes shouldn't matter too much (as long as it's 17,18, 20, or 22), it's when your tire goes up or down in load range that the pressures come into play. Or when towing/loading down the bed.

Finally got into the K02 club! I got a good deal on CL for these Mehtod NV's last Dec but never got around to getting them put on until now. Lost a little power to the extra rotating mass but it was less than I had feared. Rides better than my stock 20s did so worth the trade off!

      Scan Tool Recommendation

      By CamGTP · Posted

      I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
