Max tire size, please comment

Hello. I'm thinking about putting BFGoodrich All Terrain T/A or Bridgestone Dueler AT both sized at 285-75-16 on my stock 16" crome wheels for the 1997 Ford Expedition 4 wheel drive. The dealer said I would be fine. Any comments from the experts?? Thanks for any help.

Dave

33 10.50's refers to the tire size... 33inches tall and 10.5 inches wide... respectivley... If I might make a suggestion...
You ought to look at the Yokahama Geolander AT+ 285/70/R16 These are great tires... Hi performance design with an aggressive tire pattern... My good friend just installed some on his 99 explorer... WOW!!!! what a difference the tires make... Improved truck ride and handeling.....Plus with the tread allows him both on/off road capablities......

I'd give this tire a try... Not to mention great price.. and tread life....

Tirerack has the Yok's for 113.00 per tire, with free shipping and no taxes if you ship from Louisiana. MAJOR BARGAIN!!!

I've got the LT 285/75/16 Dueler AT's on my stock 16x7 inch rims and everything is fine...no rubbing at all and you wouldn't believe the looks now. If converted to the inch system these tires would be 33/11.2's. I got my as replacements for the Wildernesses for $113 each from Discount Tires. When it was all said and done, the five tire replacement, stems, and balance only cost me $32.

Did you have "P" tires on before? If so how did your ride quality change? A dealer here is telling me that I will hate the ride if I go to this type of tire.

What size tire did you have on before? What size rear end do you have? I have a 1997 F150 with a 4.6 V8 automatic & a 3.55 rearend. With the noticable change in tire diameter there will be a speedometer error which I can live with (I am installing a tach). What I might have an issue with now, is that I will effectively have a lower (numerically) rear end. Have you noticed any reduced accleration off the line. On the other hand you should have better gas milage on the highway.

Snifferdog, I had the standard P255/70/16's before the new Duelers. My ride quality improved at least 3 times compared to the Wilderness tires. I also installed a single shock steering stabilizer and that also improved steering reponse. What I like best is that the taller 75 series tires fill out the entire fender area of my 4x4 whereas the lower profile 70 series left huge gaps.

I don't know what my rear-end ratio is, but I'd guess it is probably 3.55 or so. From prior research, I understand that my speedometer is off about 10 percent, although I can live with that...even the wife can compute 10% of just about any speed without too much thought. If I ever get tired of always figuring my speed, I can always install a new gear for about $15. Yes, the acceleration off the line is a little more sluggish, but not too bad. I have the 5.4L and it is plenty strong for my driving style.

FYI on the transmission gear change out. From my research the speed from the transmission is sent out via an electronic signal pulse. Much more difficult to correct now. I believe the only 2 ways to do it are a customized performance chip or superlift ($200) offers a module you splice into the signal wire coming out of the transmission. I have already resolved the speedo error in my mind and accepted it.

Currently I have the P235/70/16's Generals from the factory. I guess that I still can't comprehend how the ride quality can be better when you are now running a light truck "LT" versus a passenger tire "P"/

I've got to guess that it all boils down to engineering. I've owned just about every "major" brand of tire made and by far the best ride has always been Michelins...unfortunately they do not make a 285/75/16 so I went with the Duelers. Since Bridgestone offers a no-hassle 30-day money back guarantee, I figured I had nothing to lose. Another reason is that the 285/75/16 tires have taller side walls which also help improve ride. Lastly, while the new tires are "LT" type, they certainly are not the super industrial load range 8 or 10 ply versions like many former LT tires.

This is good to know. I will have to look at the Bridgestone Duelers. The one dealer who was going to sell me Coopers said I would hate the ride if I got their 285/75/16's and is steering me towards the 265/75/16's. Just curious but aren't Brigdestones made by the same people who make Firestones?

I am currently running 33-12.5 BFG muds and had to install a three inch body lift right away. I drove for two days without the lift and wasn't able to turn more than half of my normal radius. The tires are plenty agressive in the mud and ride quiet and smooth.

I just put Procomp AT tires on -- 265/75 R16 -- one size larger than stock. Went through evaluation of impacts, etc. Larger the tire, less towing capacity -- impacts acceleration some too. But with one size larger, the affect is minimal (500 lbs on towing; your odometer/speeedometer will be off (about 4.5 miles less than actual every 100 miles, whcih can be adusted by Ford if this bothers you). I would not go to a larger tire.

I am pleased with the Procomps which provide more aggressive tread for off road but they are a great street tire too with great wet road traction. (see Procomptires.com).

If you want performance tires. Then go with 285/60/16 Toyo Proxes ST. They are by far the best performance tires for SUV.

I have a pair on my truck and if you look at the truck magazine
almost all the truck have TOYO.

They are a great tire especially in the rain.

My truck handle much better.

check out wwww.toyo.com

good luck

Does anyone have input on the biggest tire you can fit on a '99 4x2 EB exp with air suspension? I like the dimensions and looks of the 32x10.50's I had on my 2wd truck and would like to get as close to that as possible.
