Is that clearance from the factory or did you go bigger and wider on tire size.
Sure hope you don't have tire separation, because it will possible tear up that slide bar next to that wheel.



Good God man, didn't you read the first post ?


Yep! I'm just like you I guess have to put in my two cents worth, and I flunked reading comprehension too.
Why would you care anyway.

I hit it with a mini hand-held roto-like air grinder (had to get the air hose out anyway)-



then hit it with some rustoleum paint



I figure the only time there could be any potential contact would be a tight turning manuever, which should be at very low speed such as backing into a site. With that sharp corner smoothed down, there shouldn't be any damage if it did contact the tire.

I'm done doing anything outside for the day, it's just too humid out there.

Probably too late, but LT235/85R16 would have been a better size choice. These carry the same load and have the same outside diameter as LT245/75R16. The tire shop guys should have known this.


I looked at that size, it's another 1.26" bigger (diameter wise) than the one I got-

I went from 28.28 to 30.46, the 235 85 would take it to 31.72, a 3.44" increase diameter was too much. I failed to check the slide side before I ordered. If I had, I probably would not have bought the 245's, and probably would have bought the 225's, but I think I might be ok on this.

They can't be the same diameter, here's how to figure it::

( ( (235 * .85) * 2 ) / 25.4 ) + 16 = 31.72

( ( (245 * .75) * 2 ) / 25.4 ) + 16 = 30.46

Took first trip with the new 16" wheels with Michelin XPS Ribs- about 300 miles round trip.

Towed very nicely. Did not see any indication of any contact, so I think it will be fine.

That is exactly why I didn't go to 16" wheels on our Wildcat. The solution I was given was to raise the trailer on the suspension which I didn't want to do; it's already high enough.

You need to really keep an eye on it since it will likely rub on rougher road surfaces, and tight turns especially when backing up.

pritch,
That is really too close. You should have a minimum of 1" clearance to account for side to side movement and that is not enough somtimes. Tires and suspensions are usually quite flexible, even leaf spring suspensions. I have a lot of experience with trying to put too big tires on a Dodge Dart when I was a "kid". I quickly learned "what not to do".
Keep a very close eye on that tire to see if that sidewall gets "buffed" by touching the bar. You will easily see if there is any contact w/ the new paint on the bar.
I don't know if it could happen but if that bar gets rotated will it put pressure on the slide mechanism trying to open or close it?
Best of luck.

I may be speaking out of turn here but we considered changing out our 15" tires and going to 16" but were told be a couple of sources that you risk changing the way the RV was made and if you are ever in an accident the investigator will look for that first. Seems like you would be opening yourself up to a refusal to pay from your insurance and possible lawsuits.

That is just scare mongering and nothing more!

You might be able to put spacers behind the wheel to gain some clearance.


Recommend - If you go with the spacer route, I would use the same size spacer on each of the wheels to keep the summitry and balance all the same. Good luck and Happy Trails . .
