Replacing 15' wheels & Tires with 16'?

We have a 2002 Lakota 28 RKD. I'd like to replace the 15' D rated tires and 15' wheels with16' E rated tires and 16' wheels, as is on my truck [235/16']. A rough measure looks like there would be only 1' seperating the 16' tires. Is this possible? Has anybody done this? Is it worth the effort? Thank you iRV2'ers.
Matt

Instead of the "standard" LT235/85R-16E all steel construction Michelin XPS Rib that is most commonly used (load rating of 3042 lbs @ 80 PSIG, 32.0" diameter), take a look at the Michelin XPS Rib in size LT245/75R-16E. This will give you the same 3042 @ 80 PSIG load rating but with a smaller 30.6" diameter. See HERE.

Yes, the upgrade is well worth it. Many users who have had tire problems with heavy 5th wheels using the LT235/85R-16E tires have switched to the XPS Ribs and eliminated their tire problems - myself included on our previous 5th wheel. I'm so impressed with these tires that I have 6 on my truck right now. They're not cheap, but the peace of mind is worth it to me.

Trailer owners with 15" wheels have an option not available to those with 16" wheels. Look here http://https://www.tiresavings.com/t...season=Regular
for 15" load range F,G and H tires. You must have rims capable of the increased air pressure.

They also list a 215 size that is only about 29-1/2 inches in diameter and the same load rating.

Yes, it's a load range E, but the LT215/85R-16E is only rated at 2680 lbs @ 80 PSIG versus 3042 lbs @ 80 PSIG for the LT235/85 or LT245/75 that I mentioned earlier.

How much space between your 15" tires? Measure at both sides as they are not always the same due to the at-rest position of the center spring mounts. The tires can't move toward each other closer than the center pivot allows, so I bet you can change the tires to 16" without a problem.

4" is plenty of room to add tires that would only be within 3" of each other--I see plenty of trailers with less than 2" clearance.
