Tire Question

[Matthew P]

are 5.00 - 5 6-ply tires larger in diameter than 5.00 x 5 4-ply..looking at retreads to keep on hand as spares, like the durability of 6-ply vs 4-ply but worried if larger diameter that there might be an issue in regarding to the front wheel well?

TIA

Look at the TCDS for which tire you can use.

THIS ^^^^^. Airplanes aren't like cars -- you can't legally just change parts without some sort of approved data.

Read the Goodyear or Michelin Aviation Tire Catalogs.  Within a tire size such as 6.00 -6 or 5.00 - 5, the 6 ply and 4 ply have the same diameter and width.   That way they fit properly within the wheel well.   Retreads change the outside sizing.

Thanks, so a retread that's a 5.00 x 5 4-ply retreat will probably be a larger diameter than a 5.00 x 5 4-ply non-retread?

Aviation Consumer magazine talks about tires on a regular basis.  They’ve stated that to meet the TSO for tires, they must still be to the standard dimensions.

But you probably still wouldn’t want to use them for a nose tire.  Balance, older age, and quality could be concerns.  At the flight school where I was a CFI and A&P, we put retreads on the mains but only brand new on the nose for those reasons.

I think so.  Some are larger than others, i.e. Desser Monster Retreads

I have known of an FAA Inspector (many years ago) who dinged a plane with 6 ply on the nose and it not being in the TCDS

I don't think today any current FAA type would even know that issue but why ring the bell?
