Effect of change from 190/180 to 160 tyre?

**R-Soul** · 10th June 2010, 16:13

Hi all
I recently had a puncture form a screw in teh back tyre. I had to chuck away a relatively new Pilot road 2. the dealer offereme a veyr cheap replacement 160 that was off a crash bike (with minor damage) . It looked ok on the rim, so I took it.

I want to know what effect eth change fo thikcness will have?
Anybody?

It does seem to turn in easier...

im guessing you'll have thinner chicken strips........

What the hell did you chuck away a tyre with a hole in it for? A mushroom plug puncture repair makes it perfectly good to use. You should only throw it away if it has stuffed the sidewall. As for the 160 it'll be okay, but it will make the bike a bit skittery.

The tread will be flatter across the tyre, and although it will tip smoothly, you will be on te very edge of the tread before you have achieved a full lean angle. If you ride like a nana etc, it shouldn't be a big problem. Just don't expect squid performance.

Mrs B tells me that it is common knowledge that the width of your rear tyre is directly related to the size of your penis. I'd be inclined to take that tyre back and punch the seller in the face.

It will square off as it is made for a 4.5" rim not the 5.5" of the VTR . If pushed hard it will step out as you ride off the edge of the tyre .

You know that crashed bike it came off ..... it crashed due to a undersize rear tyre!

Ok I made that up, but .................

As riffer said, if the puncture was in the treaded part of the tyre and not made by an overly large object I'd be going in and asking for the tyre back (which they've probably since sold for way more than the amount they sold you the 160 for). A mushroom plug fitted from the inside will be prefectly acceptable for the rest of the tyres life.

Um, not a good suggestion I'm afraid, and only really an option if there you are stuck with nothing else.
The 160 will flatten it's contour far too much on the larger rim that the 180 and 190 are designed for, which isn't so bad for durability because of the increase in the size f the zenith of the tyre, but really leaves you short on contact patch at any sort of lean angle, and short of grip because of that.
I wouldn't be pushing the thing right now, and it would be best to get the correct size tyre back on a.s.a.p

Yeah teh bike shop tried averything they could to save it - but it would not seal - the screw had gone in diagonally and close to side wall apparently.

I only go for more leisurely weekend rides at street legal speeds , and commuting. So I guess I do ride like a nana on it (or will do for the time being- but have track days planned for next year). I hope to have new tyre before then.

As a note the 190 was overtyred (unless they have a 6" rim). I'd bet on a 5.5" (will be on rim) it should require a 180

I've only got narrow tyres on all my bikes. Oh and I've got a really small penis.......
