Tires and Wheels

• 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.
• Decoding a Tire's Numbers
• Tire Article - whys and wherefores - ST vs. P, etc.
• Another Tire Article - good stuff (thanks Bob C.)
• 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. Click here 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)
• 15" 5 bolt on 4 1/2" 5" wheel
• The original wheels are 5" deep--most wheels today are 5 1/2 and 6". Be aware, deeper than 5" may not fit. The wheels linked above are perfect.

William G. reports that 1979+ Scotty LITE models have 13" wheels with a 4x4 pattern. He offers up the following information, if you are looking for used 13" rims. William adds do use caution to have a competent mechanic or tire person check the rims prior to mounting a tire to assure that the center hole is the proper size to allow the rim to mount properly on the hub and that the offset is the same, or very close, to the original rim offset.
