Hello all, I'm Brian, pretty new here. Had my 2003 Super Crew Short Box 5.4 4x4 for about a year. It has the chromed steel XLT wheels and I want to keep them on it. The issue I'm having is I want to put the tallest tire on there I can fit without any leveling/lifting. It has 31's now. I want 35's. I know 33's fit, but can I squeeze 35's in?

Also, I'm looking at 285/75/R16 (32.5 tall) Dunlop Rover M/T Maxx Tracs

Any thoughts/reviews on these? I live in C****** Ohio, heart of the proverbial "Snow Belt" east of Clevlend Ohio, so it must do better in the snow than in the mud. Also, I'm trying not to break the bank.

I've searched many, many pages here without finding some variance in the situation. Any thoughs toward mine specificaly are appreciated! Thanks! Brian

 

I can't help you with that specific tire, but the size will work with no issues. I have been running 305-70/16 for well over 100,000 miles on my truck with no problems.

 

I have a 02 and stepped up to 285/75 R16. I think that is about as big as you can go before you need a lift kit; so they will not hit the wheel wells when turning.

 

Unfortunately, I too cannot offer any insight on the tire, as I have never run it myself. I can however offer the following....

Being that you have an '03, if memory serves me right, your truck will have the older style full leave suspension (God, i loved that suspension)... that being said, the 315's will be awfully close. 285s and 305s should fit fine.

I had a 2000 and 2002 that I ran 315/75/16 BFG ATs on for years, but I also had the leafs re-arched and added a leaf at all four corners. Even with this mod, I had ever so slight rubbing on tight, full-lock corners (but not during normal driving conditions). I also had a 2006 that I ran 315/70/17's on with NO mods at all....

Not sure if this helps at all......

 

Looking into the matter further, I have (as can be seen in my new gallery ) that I'm running 285/75/R16 offbrand M/Ts and they look small (90% of the tread is gone keep in mind.) I thought these were 31's but it looks like the size would make them 33's. I'm going to shoot for 305's and go from there.

 

Considering that your XLT (OEM) wheels are 16X7 in size, you may want to stay with your current tire size.

Size: LT285/75R16
Sidewall: OWL
Approved Rim Width: 7.5"-9"
Section Width: 11.3"
Outside Diameter: 32.8"
Max Load: 3,750@80 psi

Size: LT305/70R16
Sidewall: BSL
Approved Rim Width: 8"-9.5"
Section Width: 12.2"
Outside Diameter: 32.8"
Max Load: 3,525@65 psi

If you compare the specs of both tires, you see that the "Outside Diameter" is the same at 32.8 inches. However, the "Section Width" is an inch wider (12.2") on the LT305/70R16 tire, which requires a wider wheel width (8" minimum). Although it can be done, there will be bowing of the sidewalls due to the more narrow 16X7 wheel. Also, it appears that the LT285/75R16 is an "E" rated tire and the LT305/70R16 is a "D" rated tire. I base this assumption on the "psi" level at "Max Load" which is 80 psi versus 65 psi respectively.

In short, you gain nothing by going to the LT305/70R16 tire and may lose handling and load capacity... just something to think about.

 

BTW, nice looking Super Duty!

Size: LT295/75R16

Approved Rim Width: 7.5"-9.5"
Section Width: 11.73"
Outside Diameter: 33.27"
Max Load: 3,415@65 psi

It's listed as a D load rate, but carries the same weight as a 265/75/16 E rated tire. I'm no tire expert so I can't tell you if the load is equal or not.
