I have a 1986 CUCV m1008 and am in dire need of larger tires at a good deal for speed increase. Me and my friend will be putting a high amount of miles on the truck a few months at a time ( its absurd but we chase storms ). I have been a lurker on this site for a lil while and everyone on here seems very helpful and knowledgeable when it comes to modding CUCV's/Trucks. We are thinking of mounting 37' hmmwv tires and wheels, or just buying the wheels and mounting larger tires on them. What are some other expenses that may come with this upgrade ? We are also thinking of a 4 inch lift kit with the tires. Do we need spacers still? or will we have to get them re centered? these are just some things I have heard we will need to do. Honestly we will be driving the hell out of this truck and would like to mount the tires with the least amount of money involved because we are on a budget, but of course not at the expense of safety or drive-ability.

any other advice or suggestions in relation to this would be taken and appreciated as well :D

thanks

If you install the lift, look for some tall skinny tires to install on the stock wheels. 9.00 x 16 or 11.x16. If your chasing storms in the midwest you can find these size tires all over at farm and feed stores throughout the heartland. Google Co-Op Grip Spur tires and you will see what I mean.

I think Humvee tires and wheels are too heavy for your needs. Go with the taller narrower tire for high mileage driving load range E. would be preferable.

I would get another vehicle.

I have a CUCV that I love however, I sometimes fear that when I will go to turn the key that it will not start.

Also, on long trips it gets a little annoying not having A/C, listening to the engine struggle for 65, and wandering why you didn't just start with a K30 and build it the way you wanted and saved the extra cash.

Steel wheelspacers torqued every 100 miles or so would be the least expensive way to go. Wider dually hubs and rear axle are easy too but the tires will stick out about 2.5" all around. Recentered wheels are probably the option but run about $800-$1100 per set.

If you are going to run the military tires, find ones that are like new and have no dry rot or cracks on the sidewalls. For storm chasing I would keep the rubber runflats too. I run 12 and 24 bolt wheels and 37" Goodyears and love them. I have wheeled at 0 psi on the runflats with no problems.

This is a 1986 with a dually Dana 60 and surplus h1s/37s and 8" springs (ignore the rear tires). 4" lift and trimmed fenders would be better, or rear springs up front.

I was running stock H1s and 37" Goodyears on a 60 and 14 bolt for a while with 2.75" spacers. I'm now running Dually hubs up front and spacers in the back with 39.5 TSLs, I'm planning in installing a late model 14 bolt with srw hubs at some point though. Here's a pic or two of the truck with spacers:

if your looking to gain top end speed then bigger tires are not going to get you there. i know therotically the bigger the tire the further you will go per revolution but on the flip side the bigger the tire the more weight your engine has to turn. most likley you will actually go slower with the engine you have and a bigger tire.....imo......you will not be able to make the truck go much faster (top end) than it already is.
