Why the r15 tyres are thin than yamahar6 - Cycling

I would say No. The 215/70 R15 tyres have a deeper sidewall size so it is a slightly bigger tyre. Fitting them can give a false reading at your speedometer. What year is your vehicle? I might be able to suggest the correct factory fit sizes.

Do you normally fit 195/70 15 tyres? The tyres would fit, BUT the 195/65 R15 tyre is actually smaller than the 195/70 R15 tyres. The rolling surface, the area with the tread marks on, is shorter on the 65 size tyres. This will make your speedo read at the wrong speed and might affect the handling.
This is what the numbers mean. 195 = width of the tread across the tyre in mm. 65 = height of the side wall as a percentage of the tread width, (65% of 195mm). 15 = diameter of the wheel rim in inches.

Yes, your aspect ration of sidewall will be a little larger .. (higher profile), but they will fit. Check this link for more info from tirerack:

Hi I found this on the link below

Skoda Rapid uses 185/60 R15 tyres, for these tyres recommended tyre pressure is between 32-36 PSI. 36 PSI will give you better fuel economy while 32 PSI can be used for a smoother and more comfortable ride.
Here's the link......CHEERS..

Hi Anonymous

Your best answer will be found on the tyre the manufacturer will state what the pressure should be but a general guide for an unloaded car (IE no luggage etc) with normal day to day driving conditions would be
front; 2.1 bar, about 30-31 psi
rear; 1.8 bar, about 26 psi

Hope this helps
Kind regards

Unfortunately the you are constricted by the width of the swingarm.

The tyre size for the R15 is the optimum tyre size for performance although it does not look as good as chunky tires.

Isn't performance more important than looks anyway though?

Short answer to your question... No, this can not be done.

No, from what I think you're saying, the bolt pattern is different and those wheels will not fit.

The tyre size is governed by the rim width and the space available in the wishbone. I would measure the space available for the tyres width right up inside the wishbone along with the tyre size that you have at present.
The tyre can be oversized but watch out for slipping on the rim of the wheel!
Consult a Yamaha Workshop for specialist tyre sizes and compounds. Pirelli make some super sticky tyres alowing for excellent high speed cornering!

You are governed by safety. The hub width will determine the maximum width and type of tyre as will the width of the rear suspension/wishbone.
Consult a qualified tyre fitter for accurate sizes. Don't forget your speedometer will no longer be accurate!

It’s overall length is 1070mm, overall width is 670mm and its wheels base is 1290mm. Since sporty YZF R15 is shorter too and its height is just 1070mm. YZF R15 150cc features F 80/90 -17 inches tyres in the front and 100/80-17 inches tyres in the rear
