It's time for tires. Shinko 4.10-18 actual size?

I have to get new tires. I really want the shinko 705. Ever since i rode a friends bike with and with out these tires, I'm hooked. I loved the way these tires handled. With his old tires I had no confidence in high speed corners. Not an issue with the 705s.

My problem is I have 18" rims and they only make 2 sizes. I ride the snot out of my 75 CB360. It is currently shod with some 4.00s. I know the 4.10 will have no trouble in the rear, maybe even the 120. But the front is a different story, the 400 in there now has just enough room between the forks. I'm hoping the 4.10 is a little narrower than listed as often happens with tires. I've been searching over an hour to see if actual size was mentioned in any reviews, but no luck.

Anyone have this tire so they can measure?

I would stay stock size or SLIGHTLY larger in the back since those rims are made for a max tyre width of 4.00. I wouldn't go more than 4.10. The larger tyre might wrap and give you an undesirable profile where the center of the tread is fl;at and has too much of a sharp radius transition to the side. My 1973 CB350 and the CL350 (1969) both have a 400 8 on back. Perfect for these little light bikes. The smaller tyre is also much lighter and better suited for the suspension and power delivery.

I'm not wanting to go really big. But this is a rat rod cafe bike. I want a wide tire in front. My trouble is I'm worried the 4.10 might be too wide for the forks. I have a 4.00 front and rear now and the front has just enough room. The Shinko 705 smallest size is 4.10. I'm hoping someone has the 705s so they can measure the width to see if it is really the size it says.

I know that car tires are notorious for being smaller than advertized. For a change, I'm hoping this is the case with Shinko.

I have a 4.10 705 on the rear of my XV920, I'll try to remember to measure it for you. The front rim on your 360 is probably a WM2. The rear on the Yamaha is a WM3 and the tire is fine . It will be pinched somewhat on a WM2 width rim though , I'm afraid.
The front of my Yamaha has a 100 /19 705 and works great. Any chance of swapping your 18"
for a 19"' for better tire selection ?

Yes, please. if you could measure your tire it would give me a good idea if it will fit in between the forks.

I don't know about the 19", I can look into it. I haven't tried. I don't know if I could find one that will fit. Might look funny on a cafe bike. But it's only one inch. I'll see if any friends have one they will let me test fit. It's the same wheel the 350s use. Know of any with disc brake that might fit with alloy rim?

A 4.00 and a 4.10 are the same width. The .1 is how they designated low profile back in the day. So let's do a little example:

Metric is a 110/100/18 - this means the tire is 110mm wide, 110mm tall (100%) and 18 inch rim.

Std is a 4.00/18 - this tire is 4.00 wide, 4.00 tall (standard 100% aspect), and 18" rim.

Low Pro Std is a 4.10/18 - this tire is 4.00 wide, 3.28 tall (82% aspect) and 18" rim.

This is the same for 4.10, 4.60, 5.10, 5.60 and 6.10.

So your 4.10 will fit width wise, but it will be noticaby shorter (making is looke narrower.

Oh! I guess I never understood standard sizing. Metric sizing I know. Well that's cool! Thanks, you just made my day. A lower profile is actually what i've been looking for. I almost went with a different tire in metric sizes, but I wouldn't have been able to match front and rear. Plus the reviews on the 705 are great.

Thanks again. This has been a pretty good day for my bikes. I finished a motor swap in the cafe (it runs better than ever), a friend is letting me use his motorcycle shop to finish up a long time project for two weeks while he vacations. All I need is a "mouth hug" from the wife and it will be a great day!

Did you get the Shinkos?

I have a cb360 and would love to put these tires on to. Specifically the front. Did you use these and if so could you send a pic and tell me if it was a total pain in the ass? Thanks much!!
