Right now, I'm running 29.5 inch tall radial slicks (not Drag Radials) and they do not expand more than 1/4 inch max...
Now, I've read (but can't find the article anymore) that bias-ply tires expand a lot more than that.. However, I don't know how to figure out the exact amount that they expand.
The reason that I need to know is because I'm thinking in switching to a 29.6 inch tall bias ply tire (ET Drag 29.5 x 10.5W - 15)
and I don't know if it will clear. Right now, I have just over 1/2 inch clearance with the 29.5 inch tall Radial slick and I wonder if 1/2 inch clearance is enough? Does anyone know?

They are mostly talking about huge backhalve car tires.. I don't think that a 28 or 29 inch, 10.5 inch wide tire will grow that much...

That makes sense with a 10.5 tire.

1/2 inch is not near enough. They grow alot more than that. I have run that exact tire and they rubbed bad on the camaro. I had to do alot more clearancing.
