CB175 tires

[cb175]

Will this size tire 130/80/18 fit on my stock CB175 rims? Also, what is the widest tire I can run on the front without any modification? I am getting confused on what size tire will fit my ride.

Thank you in advance....

I really doubt it... That's much larger than stock, it will rub like a mofo if you can even get it on the rim. The biggest you probably want to go is 110/90, but even that it a bit big. It's also bad for handling, and too much contact patch on a small bike means less speed both in corners and on the straights.

I'd recommend 90/90-18 in front and 100/90-18 in the back.

Something like this

the rear tire that came on my 175 is 3"

Yep, my tires are 3.00 - 18 in the rear and 2.75 - 18 in the front. I don't understand all the 110/90/18 stuff. I know, I sound like an idiot but I am new to this. I finally got my permit today.

Anyone know the answer to my petcock question?

Thanks for the responses.

I'm not sure if it has WM0 front and WM1 rear rim (maybe WM0 both ends?)
WM0 is only 1.4" inside flange.
Isn't stock tyre size is 2.50 F & 2.75 R ? (or did that one have 2.75 & 3.00?)
Either way, 2.75"is only 70mm (near as dammit) and 3"= 76mm so even a 90/90 (90mm x 90%) is too wide for rim ( or at least, right on limit)
Narrowest rim a 130 should be put on is 2.5" inside flange (WM 4) even that is on its limit.

90/90-18 is roughly 3.5 inch wide by 3 inch tall.
100/90-18 is roughly 4 inch wide by 3.5 inch tall. It's bigger than stock, but it's the only size that will fit and where you will still find tires. A lot of people on here are running bigger tires than this...

OK, I actually understand this stuff and understand what problems you will have if you try riding hard with oversize tyres on narrow rims.
Maybe plenty of people do it, they usually have no clue what they are doing and its more luck/reflexes that stop them getting hurt.
To convert from inches to mm multiply by 25.4.
3.00 x 25.4 = 76.2mm
A 3.00 x 18 trye has a 'natural' distance between beads ( the bits that hold tyre onto rim) of about inch and three eighths, which is real close to 1.40".
A 110/70x18 has a distance of about 3.00", and, guess what?
That's the rim designed and recommended for it.
Its possible to fit a quart in a pint pot (just freeze it ;D) but, your in trouble when things warm up
If you 'pinch' the beads thre tyre will flex and roll on rim, plus, it will wear out way faster than if fitted to correct rim

Avon give recommended rim widths for tyres, plus alternatives

Continental actually list 2.75 x 18 and 3.00 x 18 tyres, if you want to upgrade that far.
this may link to catalogue download, several different 3.00 x 18" tyres

I didnt check other manufacturers but I'm sure Bridgestone, Cheng-shin, et. al. have them.

Its pretty retarded to tell someone to fit a 110mm wide tyre (110/25.4 = 4.33") on such a narrow rim, particularly when 'correct' size tyres are available.
If your going to trailer it everywhere so people can 'Ooh, Ahh' over it, go ahead, if you actually want to ride it, stick close to stock, unless you change wheel rims to match tyres

Cool,you obviously know more than I do about this. Weird though that I have seen many charts that say 90/90-18 is the replacement for 3.00, and 100/90-18 is the replacement for 3.25-3.5. here's a few more I found just googling for this.

It's very hard to find tires, especially dedicated rear ones, in 3.00-18 or even 3.25-18. I have a Cheng Shin on my CB175 in front and it's actually pretty good. The only rear I could find is in a 3.25, and it's a duro. It sucks balls. I regret not having tried a better tire even if it would have been a bit bigger.

What exact tire would you suggest?
