Tire size Q

I have a new set of 235-75 R15 that Id like to put on my 65 F100 2wd. But Im afraid they might rub. This size is a good bit taller than what's on it (215's). Putting them side by side shows the 235 to be a good 2" taller.

Id really like to use these 235s...especially since I have a 2nd set of them in the studded snow tire version. And both sets are brand new. Ive seen at least one thread where someone used 235s but is that commonly done with no issues?

It's what I have on my '66 2wd and I have no rubbing issues. I remember them being on our '62 unibody when I was a teenager.

Your 215 width seams a bit narrow in my books. What is the rest of your current tire?

P or LT 215/?/15

My F100 came to me with 235/75-15 tires and they were fine in every respect, but I guess the original 7.00 tire would have been easier to park...

Don't mean to hijack but I've got a related question. I've read at least once on here that without having P/S it is a good idea run a more narrow tire in the front than in the rear to aid in steering. Sounds right in theory, curious if anyone has experience in the matter. P/S is on the list, just not close to the top. Will be buying new tires first. Any recommendations on how much narrower in the front than the rear?? Specific front and rear sizes that have proved successful would be great, purchasing tires next weekend.

I put 235's back on in place of 255 TA's that were inflated to 32 psi. My tire guy said the new 235's can be run at 45 psi because they are HD truck tires. I do that and it's way easier to park now.

It's had 215 75 R15's on it for decades. They are a nice matched set and good even tread...prob about 70% tread remaining. But the date stamp in them is 183. So I gather that means theyre pretty old. Either 1st week of 1983 or 18th week of 2003. Im thinking they should be replaced just due to the rubber aging. But they dont show any craking or checking except in the "lugs" of the treads. The truck is from Fairbanks Alaska...the ultimate "cool, dry place".

Thanks for chiming in. I had not thought about the fact that Im keeping mine as manual steering so I should keep my tires as narrow as possible.

I was told recently that tires have a life of eight years, no matter how much usage they've had. (The only tires that young at my place are on my wife's Rav4.)
Maybe a tire expert could shed some light on this. Do we have one here?

Unless I'm at a dead stop, steering with 235's is easy enough on pavement with manual steering.
