im currently caught in this dilemma.  i dont want to pay the big bucks for the 140/80.   the 130/90 is a great price but id really like to not go down in size.  so will the 140/90 fit??  i have saddlebags with stock brakcets, my shocks are stock and i do take the wife out alot.  

im not at all worries about performance loss/gain just purely on looks id like to have the 140/90.  but if its gonna be a rubbing situation then i wont even mess around with it the 130/90 will be it.


its an 05 s40 and i have a kenda cruiser in front already and need to decide on this rear.  any help is appreciated thankyou++++

Alrighty then,  

Since everyone is either stumped or uninterested, I'll get on with it.

Here goes...

There is a pattern found in this chart correlating with aspect ratio. As it increases, smaller rims become increasingly compatible with a given width. For example, the smallest rim recommended for a 130/60 is a 3 incher, but a 130/90 can go down to 2.50 inch rims.

Here's why-- at least in my not-engineer opinion -- Higher aspect ratios give a longer sidewall height, which allows less angle from the rim to the tread, curling the edges of the tread less., thereby giving a better profile and a wider tread compared to the smaller aspect ratio. Remember Dave's tire geometry discussion in the Cafe Tire Thread? Same ideas, but with an additional complication-- aspect ratio. (And yes, Dave, the tires are of different sizes, but the discussion is related.)

In a sense, higher sidewalls are more flexible and can accommodate more rims, while low profile tires are more picky. I bet that low profile car tires are extremely picky about rim size. Their squarish treads can't curl like bike treads, can they?

About ready to drop the money on a couple of shinko 712 rears-- one for myself, and one for my Dad's 750 Shadow. His has a worn Dunlop 140/90 on it. Looking at it, it seems like  a lot of rubber for the poor little Savage, but it's mounted on a 3.5 inch rim. Looking to get 'em from Bike Bandit and get free shipping. Are there any better deals out there? http://www.bikebandit.com/tires-tubes/motorcycle-tires/shinko-712-motorcycle-...

From what I remember, it seems that some people here don't like this company. I haven't tried them yet.

Any particular recommendations on tubes or rim strips?

Just throwing this in.Here is a 140/80 beside a 150/90

Not a "stock" fender. This 150/90 shinko 230 on my bike is on a 3.5" rim and the under fender bolts have been swaped out for button heads.



Even then the spacing has to be perfect. 78" roll out really changes the gearing. My pulleys have both been changed, moving the axle back in the slots. Might not clear the swingarm, or front of the fender with stock pulleys.
I'm not sure if a 140/90 will clear if you just change the front pulley. Anyone tried it?

To modify or correct the ideas I mentioned, the chart also seems to suggest that higher profile tires don't fit very wide rims as well compared to low profile tires. It seems that low profile tires like large rims and high profile tires like smaller ones.

Thanks for the review on Bike Bandit. I'll probably end up buying from them.
