cooper stt

i have an 01 xlt ranger v6 4.0 5speed, and when i got it i bought a set of 265/75/16s cooper stts. stock were 245/75/16s. now i think they bog down my truck, and i think it is what made my clutch blow because i haul a trailor alot with it for my buisness. anyways is anyone else having this problem or is it just me cause i am an idiot. if anyone can tell me something to solve this problem or anything, that would be a big help. thanks

265's are just below a 32" i believe. With the 4.0 I dont think it should bog down your truck at all, or at least not anything significantly.

I dont think it was the tires i think it might be a over loaded trailer, or not to be rude but maybe improper shifting.

well maybe i have something wrong with my truck anyone ever had a similar problem that something was not right with the truck itself. i dont really know all i know is it does bog down. and the trailer is only hauling about 700lbs maybe 1000 once in awhile. and i think i know how to shift..lol..maybe not.haha..im not trying to be rude either i agree with you..lol

I dunno guys, i found my 32's (265/75/16's) definatly bogged down my truck. I dont know if i notice it more because i have a 5 speed, but I can definatly feel it hunker down in the gears, and i find i have to downshift alot more that before.

Off the line is noticeable, and i know if i were towing a trailer i'd feel this more.

Im hoping an Xcal from Doug is gonna fix this up. Maybe an exhaust too.... cuz my truck is a dog now.

Moving to bigger tires will always have some negative impact depending on what gears you are running depends how big of an impact. Look on your door sticker, you can see what gearing you have.

How do those cooper stt's handle off road and in the snow. Check your gearing like others have suggested. Did you put steel wheels with the tires? They can be heavy and cause some "bog" down.

the cooper stt's are a great tire i think. i got a great deal on them and wore em down pretty good. in the mud they clean out well and the snow they seem to do good they dont like ice but god what tire does anyone who says tires do well on ice is smoking something. i am going to get a new set i beleive this week but they are a bit expensive for my "college" budget and they do bog down my truck. so i am still deciding. i put them on with the stock 16 wheels that came with the truck.

Your truck is older, thats out of a 04 manual. You have the 7.5 rear end with open diff and 3.45 gears

I just bought a set of 31x10.5x15 Cooper STT's, but won't have them installed til next week. They look like a very aggressive read that will cause some extra friction/drag, but not enough where it will bog the truck down significantly. Are you running heavy rims?

i would have to agree with everyone else.. prolly and internal issue, possible bad slave cylinder that wasnt replaced when needed .etc.. those tires even with stock gears isnt gonna do any harm

I just had my clutch replaced, and I did notice bogging/hesitation when acceleration and shifting gears. Now that its replaced,it drives better than its ever felt since I got it.
