I did a little searching but couldn't find exactly what I wanted and it's 88 degrees in my house, the water is off due to a break in the main up the road and I'm sticking to everything. Needless to say my head ain't operating normally...

I have a 05 XLT with 255/70R17 Generals and 3.55's. My question is about the Revo's. Can someone tell me how wide the tread pattern is on a 265? I'm strongly considering these, but not sure it'll make any noticeable difference in the "looks" dept. I'm a little worried the 265's will have a wider "bulge" and about the same width tread as my Generals. I'm hoping the 265 Revo's have a noticeably wider shoulder, do they? I'd love to do 285's, but not sure it's a good idea with the 3.55's even with an Edge. Again, my apologies for another useless tire thread...

 

Go to www.discounttire.com. They have a tire size chart and calculator on their site.

 

Here are more calculators..
http://www.ring-pinion.com/content/calculators/RPM.asp

There are many tire aspect combinations to get close to the width and tire height you want. i.e. You can go to wider width, say from 255 to 285, and actually a lower overall height by changing the series say from a 70 to a 60.

You can use the calculators to get to as close to the overall width and height you desire and then see if they make a tire in that width and series.

You will find that there are popular tire sizes and these will be the cheapest.

You can also plug height numbers into the other calculator to check RPM changes at different speeds with different tire heights.

 

I can't speak for the Revo's, at 255 going to a 265 will not make much differance, I had p235 70 17 on my 04 F-150, Than I put LT 265 70 17 BFG, performance and mileage were a 1000 X improved with a 355 LTD slip, the OD and speedo were more acurate with the 265 tires 70 17 tires ...

 

Thanks guys. There isn't much difference between the 255 and 265, but if I'm going to replace them a little wider and a little taller is the way to go. Wonder why there's no 275 for the Revo? I kick myself for getting 3.55's but someday gears will be upgraded, then maybe the 285's will be on the list. Only thing left I'm worried about is if the Revo is more "square" in the shoulder, the Gen's are fairly rounded off. I'll have to stop by Firestone and take a lookie.

 

355 is not so bad...great for the high way, not so good from a standing start, I towed 5000 LBs worth of cribbing Forms with my 04 F-150, and the Truck hauled it ok, even with the 265 70 17 tires..

Now my new truck with the 373 is a towimg monster whem compared to the 355 in the 04 F-150, only knock I have with the 355 LTd slip is the auto trans in the Ford is totaly lost when shifting down for more power, ( Empty ) RPMs go up and two to three secs before you move...And I had the Ford dealer reprogram it the coumputer, anothier reason why I want back to a manual Transmisson.

 

Try this site as well. Compares both sizes and tells you in MM and inches.

When my truck had about 500 miles on it, I put on some new Mich 265/70/17's.

I like them.
