14.5+ NE: TKC 130/80-17 Rub on Inner Fender

Hey folks,

I have seen mention here of larger rear tires rubbing on the exhaust and chainguard, but I found on my 2016 that the TKC 80 130/80-17 is ~8mm from the exhaust (plenty of clearance) and I easily bent the chain guard slightly out of the way. However, the tire IS rubbing on the inner fender on the left side when the suspension compresses and the tire enters the, for lack of a better term, "narrow zone" under the rear fender. My exhaust is not even moved out using washers, as many have done. The tire is also perfectly centered in the swing arm, with about 8 mm of clearance between the widest part of the tire (ends of the knobbies) and each side of the swingarm, so I know my rim is not misaligned on the hub. (Also, all three of my spacers on the rear axle are in the proper location and orientation).

Note that per Continental, the 130 TKC is actually 141mm wide...5.6 inches. Big surprise it rubs.

Off come the TKCs to be sold with only 250 miles on them. They will be in the Marketplace on this site in case folks near Sacramento are interested.

On will go a set of 4 ply Shinko 244s that are 128mm wide (actual), as measured by my friend who has them on his '09.

Problem solved!

Keep your TKC80s.

Notice the TAB which supports the fender, wiped the fender clean of mud? The inner fender can screwed to that tab or zip-tied to the frame rail to keep the inner fender away from the tire.

pdwestman, thanks for pointing that out!

It is a hard push to move the inner fender to the left, but I could trim the inner fender where it touches the airbox as seen below the clean spot in pic 606, and thereby gain about 5 mm or so clearance. That would give me a minimal clearance that could work.

However, I will change out the tires for two reasons. First, I like having a bit more clearance all around the tire to clear detritus that gets kicked up by the rear wheel. I didn't realize the TKC would be so much wider than the stocker in the same size. Second, and this is the principal reason, I want the 4 ply sidewall of the Shinko. Frankly, I didn't check the ply rating of the TKC and was shocked to discover that it is a 2 ply sidewall. My bad, for sure.

I am working to clear some handling issues on the bike and the two ply sidewalls are very flexible and not helping my handling issues. Plus, I like having stronger sidewalls, and thus being able to run less pressures than with weaker sidewalls for an equivalent support level.

If I didn't have the handling issues going on, I would suck up the "less room", cut the inner fender, move it over and secure it, keep the TKCs and ride the mother! However, with the handling issues, I can't take advantage of the knobbies anyway. Perhaps I will keep them and install them when I get the bike squared away.

Thanks for the input!
