DRW tire size

I have a 1999 F350 DRW 4x4 with the factory aluminum wheels and 235x85x16 tires. I have an opportunity to purchase 6 new tires at 40% reduction in price in 265x75x16. The fronts I know will fit OK but will the rears fit as dual wheels or do I need to use spacers to gain the needed clearance and is this a good practicable idea?

I'm pretty sure the 265 tires need a wider rim, if I remember right on my 2000 the 235 we're a 6" rim and the 265 had a 7 or 8" rim.

Seems confusing to me, in the chart above it says 235's need 10.7" "dual spacing" and 265's need 12.2" of "dual spacing". What exactly is "dual spacing" and where is it measured at?

​​​​​​I believe it's the center line to centerline of the tires or wheels depending on where you measure it. Looks like you will need another 1.5" spacing for enough clearance.

You want the wider rims too or when at full pressure the tire will be "bent" in the tread and wear the center more than the outer portion. LT's are not as forgiving as P's on this, they're built stiff for high loads and don't appreciate being narrowed.

So who makes a 7" wide dually aluminum rim with the proper offset for our trucks? Had decided to just buy another set of Michelin LTX's in 235 size but now I find out Michelin dropped that size and my choices are 245 or 265's.

Michelin offers two light truck / commercial / RV tires in the LT235/85R16 size that each have different attributes, and that are both arguably superior than the LTX.


If you are looking for a 3PMSF rating in a tire that has curb guards and interlocking sipes (unlike the LTX), then check out the Michelin Agilis CrossClimate product flyer .

If you are looking for steel sidewalls (not just tread plys) similar to F-450-F-550 commercial tires, but in the LT235/85R16 tires size, then check out the Michelin XPS RIB product flyer.

There is no need to change wheels in order to run a Michelin light truck tire. The OEM stock wheels will work just fine with the two tires shown here.

Thank you for the information regarding the 235 sizes availability. My local Michelin dealer is ordering me a set of the MICHELIN Agilis CrossClimate tires and at a reasonable price of $268 each. Last set of LTX's lasted 47,000 miles and still going strong with maybe another 7-8k left on them.
