Bigger footprint = more > traction no? Only to a point.... You will reach a footprint size that grabs the ground best for the 'weight' of the vehicle. Once you pass this point, you are lowering the PSI on the ground contact patch so it takes less power to break them free from the ground. Normally this footprint is what the dealers list as the largest 'stock' tire or in my Cherokees case, a P225. Go wider and you compromise looks for traction. This is one reason wide tires have to be aired down to grab. They then dig the sidewall edge of the tread into the ground and get two narrow edges grabbing strong so the center float isn't as bad. Leave them hard and you go nowhere fast. Unless they are 'really' wide 'floater' tires, the average 'wide' tire on a 4x4 is just pure looks, not performance. When we have to travel in the snow, we now leave the Cherokee home because of the compromised traction and take the CJ7 with it's tall skinnies that grab the road way better. The CJ7's 'footprint' is a 7.5" wide tread on the 33x9.5" tires. The Cherokee's P235's are over 8.5" wide at the tread. Look at military Jeeps. If wide tires were even slightly better for traction, those GI's getting their butts shot at would for sure have used them... Same for folks like loggers that work in the bush. They all run tall skinnies on their trucks. One of the many other folks from this group that run tall skinnies is Steve Seppala and he was at a mud pit competition with the 'big' boys. They convinced him to try the mud pit and he made it easily where they were getting stuck. One of them got stuck, so he hooked up and dragged him out no problem rather than wait for the tractor to come over. He then told them about his missing front driveshaft that was home broken in the back yard...... Mike |

Re: gears ot tires
There is a case to be made for higher gearing and skinny tires... My
'43 GPW runs 32 inch tires (no lift needed) with a contact patch about 5 inches wide. The crawl ratio is only about 29:1, not very low. This, coupled with a weak stock motor (54 hp) makes sure the tires never spin so the jeep never loses traction. The only way it gets stopped is when the engine stalls (happens more than I would like).

Re: gears ot tires
Rather than change the tires, change the engine:

Re: gears ot tires
No, the wider tire footprint tends to "float" on the snow. The slightly
narrower footprint digs in for better traction.
