Hey Everyone!
I just bought a 06' S40.  It's in pretty good condition, but the tires are worn.
The rear tire won't even pass a safety check, and the front tire isn't far behind.
I had a question, I've been having a hard time finding a straight answer on.
Can you use a 130/90-15 tube on a 140/80-15 tire?

I can only find a 130/90-15 where I live, and was trying to avoid ordering offline.  

The stock rear tyre is something of an orphan size. According to the techies on the site, and I'm not one. A 140 90 15 is far more readily available and apparently makes the speedo more accurate. The Shinko brand in this size apparently represents excellent value for money. I'm running a Michelein myself.

I rode hard and went through a rear tire a year, I ran about 5,000 a season, Texas has long seasons and I had good gear,so, some cold weather riding,too. I never got around to the Michelin, wish I had, I DO know that they made a huge difference on my car in the early 80's. I ran the Dunlop, and it never gave me the "I'm about to drop you" feeling the stock tires did.
I USED that insecure feeling to learn to ride in low grip places. I hated that tire,but knew it was teaching a valuable lesson. My riding style changed so fast when I ditched that piece of crap,, I got a cheap, GRIPPY,tire that made about 3,000 miles, went for another, it died in about 2,000 and didn't feel as sure footed, so, I started spending more and tried the Dunlop, if I was still riding I'd try Michelin and Dunlop and decide..
Orr, go Darkside, and stop changing tires every 5,000 miles..
But that's a whole nother topic.

This reminds me, I did the 140/90 thing and have some rub, and no one local has button head bolts
anyone have a resource?

Thanks Dave, I could not for the life of me remember the McMaster site
Fastenal is a new one for me, will check it out too
