Thank goodness my stock front tire is worn enough to justify buying a new one. Since the feedback seems to be good on the Shinko 244 5.10” that is what I am getting.





My questions are about tubes. What size/brand Heavy Duty tube would you suggest for the 5.10”?



1) Is it even a good idea to use a heavy duty tube? I would like to have one for off-road use but the AMT website says: "** NOTE: Tube listings denoted with HD, Heavy Duty, or Ultra Heavy Duty, etc. are NOT recommended for street use."



2) I see that PalmStateCrawler and Spud Rider both mentioned Heavy Duty Bridgestones from Rocky Mountain ATV – however, I don’t see any of those tubes that are as large as the 5.10 x 18? They have a 110/100x18 listed, but it would seem like I would want a 130mm to match the 5.10”?



3) I don’t quite understand the metric sizing. AMT says that a 130/90 is equal to a 5.00/5.10. What am I missing? I would think 5.00/5.10” would = 127/130mm by just doing straight inches to mm conversion?​



(I am a returning rider and the last time I bought tubes they didn't have this interwebs thing - you just went to the local Yamaha shop and they gave you whatever they had and you darn sure better like it because there weren't any other options. They said "Here" and you took it an you were glad to get it - even if it was a total pieces of junk).



Any suggestions?

the stock tube should be fine as long as you don't run it too low in the rocks

I have a heavy duty in my shinko and ride streets also. I never saw that on the box. I am not sure why it would not be suitable for the streets but no problems in over 1k street miles. I bought and had mine installed at cyclegear. There is a cross reference chart there that specifies which tube for every size tire except for the 180 of course. I had to order that one.

I also tried AMT when I purchased my 244 tire in the 5.10x18 size. Saw the warning spent some time searching as to why

did not find any reasons. I can take a guess it has to do with heat build up, but that is a guess. I ended up with a Kenda Tuff Tube from

Bike Bandit #276376 4.5x18-5.10x18 with TR 6 stem the box will also say 110/100-18 and 120/100-18. Don't know about the toughness of the

tube but it is thick, much thicker than the stock tube. With that tire and tube comination the ride was a little stiffer on pavement, off road

you do not notice.

Hi Woof - Thanks. Since this tube is 9 years old I think I will replace it when I change the tire.

PSC - good to hear that you have not had any problem on the street. Thank you for the information.

sscooter - I like your heat buildup thought. I bet that is it. I will look for the Kenda Tuff Tube - That will be the first tube I have seen that mentioned the 5.10 size. Thanks for the heads up.







It seems like most websites only list the heavy duty tubes under "Dirt" or "Off Road". Not sure if that is just because that is where they are most likely to be used or because of the warning that AMT listed (due to heat buildup?)



Thanks guys! If I do find a conclusive answer, I will let you know.

The guy at the bike shop I talked to said he could not think of any reason why you couldn't use a heavy duty tube on the road.



In case anyone checks on this thread in the future, for reference, here is the tube that I bought today. The bike shop had 3 options: Standard, Heavy Duty and Extra Heavy Duty. I went with the middle option which was this 3mm tube:
