Change tires! - 235/85 R16 to 265/75 R16

Well gang... I finally swap my tires for offroad use and firewood hauling. I've been running a Big O at for the streets and light dirt road use (in town). But now with firewood season I'll be doing more dragging and skidding of trees so I put on the aggressive tires. So I popped a few pics... post-2-13869816638_thumb.jpg You'd be surprised on how heavy the 265/75 R16 are compared to a 235/85 R16... :wow:

I wish there were more "pizza cutter" style tires available in 17" rims.:pray:

Now after running on my Cooper STT for 2 weeks and watching the MPG fall like a rock I figure i better swap back to the BiG O AT 235/85 R16... I can tell a difference in weigh of the tire by just lifting them but I figure get out the bathroom scale and weigh them... I know this is perfect but this does show a huge difference in rotational mass... Big O AT's 235/85 R16 About 7 inches worth of tread face.post-2-138698167467_thumb.jpg Weighing in at about 60 pounds per wheel.post-2-138698167446_thumb.jpg Cooper STT's 265/75 R16 about 8 1/2 inches worth of tread face.post-2-138698167455_thumb.jpg Weighing in at about 80 pound per wheel.post-2-138698167461_thumb.jpg So for a 1 1/2 inch gain of tread face that is aggressive on steel rim give me a -3 to MPG's with a total extra rotational mass of 80 pounds for all axles. So I'm back to the Big O AT's on my stock aluminum rims and I'll be back to my high MPG mark again... :thumbup2:

Now you got me wondering. I swear mine can't be 60lbs. I throw mine around like nothing. I got the scale back at apartment so have to find a jack to take with me.
