• How to tell the age of your tires - replace if 6 years or older
• Decoding a Tire's Numbers
• Tire Article - whys and wherefores - ST vs. P, etc.
• Another Tire Article - good stuff (thanks Bob C.)

• Low Cost Trailer Supply: ST205-75-D15 Bias ply special trailer tires, $43.55 each
• Coker Tire: B.F. Goodrich and Firestone 640/15 tires in blackwall and whitewall, from $97-$112 each.
• Wide white wall tires are available as a special order at Diamond Back. It adds about $100 each to the cost of the tire - they will acquire the tire and apply the white wall to it. (thanks Alex for getting this info for us) See pics of a pair ordered by an NSSO member.
• Many thanks to Kevin Y. for passing along that Tractor Supply Centers (TSC) carry the right wheels with a tire already mounted. I checked this out at my local TSC and for around $85, you can a wheel and appropriate ST tire. Use the Store Locator link to find a TSC near you.

The original Scotty tires, General 640/15, are no longer available. You can still get that size in Firestone or B.F. Goodrich, however many owners are choosing to go to a modern tire/size. Modern replacement size is F78-15ST (special trailer). Metric size is ST205/75D15. Whatever you choose, go with a bias (either 4 or 6) trailer specific tire and not a car tire. This helps prevent trailer sway. Later Scottys (1979 LITE models, at least) used A78x13" tires.

Wheels

• 15" 5 bolt on 4 1/2" 5" wheel (WH155-50E) Original hub caps will NOT fit
• The original wheels are 5" deep--most wheels today are 5 1/2 and 6". Be aware, deeper than 5" may not fit. (Courtesy of Eric - cutting it close on the clearance, they were a bit challenging to get on and off, but the 6" wide rim did fit.)

• William G. reports that 1979+ Scotty LITE models have 13" wheels with a 4x4 pattern.
