larger rear tire

[aquasition_imp]

how big of a tire, the OEM wheel can take? anyone?

To the best of my knowledge, no one on this board has even replaced a rear tire yet, much less tried one any larger. As with anything else there will be disagreement on whether the stock rim will even accept anything larger as most tire mfgs don't recommend using anything wider on certain width rims, but some owners think they know better and will do it anyway. It has been discussed on this board and some feel it could handle a 150 width tire. I don't believe anyone has suggested going as large as a 180.

My 1999 Magna VF750 came with a 120mm rear tire, and I installed a 150mm which was/is the widest tire the OEM rim could take safely. this set-up never gave me any trouble and it looks fantastic.
I think the CB1100 would look better with a 150mm tire because it is a wide bike with that wide engine block and it is asking for a wider tire IMHO. cheers.

you can do a 150 on the CB1100 wheel/Rim.

I plan on getting Avon Road Riders when my tires run out. Look at the last two rows, you will see the difference in dimensions,specs etc etc between the stock 140 and the wider 150 tire....

Personal observation; larger tire will look cooler but it can, depending on the profile, slow up the handling.

I can only speak for the German market, but here are rear tires in 160/60 dimension available from Bridgestone (BT23, T30) and they are officially released and technically approved for the CB 1100. These tire dimensions are mounted onto the stock rims.

Ingobohn..what does " technically approved" mean? By Honda or by Bridgestone? Or is it a governmental thing.

Keep in mind that there can be at least 10 mm difference in width between two tires from different companies in the same size. This depends on the profile and the tolerance allowed, I have had 130 tires on my bikes and they had the same width as a 120.

I think one thing to keep in mind here is that our bikes have radial tires( even though they are a odd size) . I don't see anything
wrong with putting bias tires on but you might have a rougher ride. Switch both.
Radials deform more when you put them on to small of a rim. So you get more strange handling issues.
Most of the tire Mfg. making a 160/60-18 in a sport touring tires are making it to fit a whole group of older late 90s BMWs.
They all had 4.5" rims on the rear. I mounted a lot of them.
I am very proud that in the last year my store was open ( 2012) I mounted right around 1000 tires myself. It was nice to go out
on a good note.

In former times, a bike had a so called "tire binding" which means that the bike was only allowed to ride with specially "released" tires. The tires (brand, tire model, size, speed limit etc.) was stated in the "papers" (vehicle registration) which each drivers has always to carry with him. In case a police checks the bike and recognizes that the bikes uses other tires than stated in the docs, the driver was fined. When an accident happened and the insurance company showed that the accident could be fully or partly avoided with regular tires, the insurance can reject paying the bills.
So for example, if the papers state that tires from brand A (model 01), brand B (model 07) and brand C (model 11) are released, you were not allowed to use any kind of tires of brand D, E, ...
And even from brand a, B or C you were not allowed to use model 02, model 08 or model 12, and so on. It was really a pity. Especially, when you just hat 1 or 2 tires stated "in the papers", so you had very limited choice. And when the tire manufacturers deprecated producing the models which are for you, you had a massive problem. Then you had to do a check at the local technical governmental authority and show that this and that tire is also safe. But this was hard to do and cost lots of bucks.

Nowadays it changed (a bit), there is no more "tire binding" for newer bikes (the old ones still have). Now it is simple stick to the dimension and speed limit. E.g. for my CB 1100 I have front tires 110/80RM/C58V (V means up to speed limit of 240 km/h, 58 means a load index of 236 kg) and rear tires 140/70R18M/C67V.
But in the road regulation laws there is still a kind of fuzzy paragraph which says that even with the right dimensions either the bike manufacturer or the tire manufacturer must state that the tire/bike combination has a so called "clearance certification", i.e. either of the two simply means "it is safe riding this and that bike with this and that tires".

This topic here is an endless story full of discussions with of course different opinions. Some say it is still enough to have simply the right dimensions, some say you need this clearance certification".
My private opinion is that I only ride "released" tires for my bike because I do not want to risk to be fined or (what is even more worse) to lose my insurance coverage.
