Default Bigger main wheels.

Did anybody try bigger main wheels on RV-10? I thoroughly searched forum but did not find a single hint. I searched Desser and Spruce but did not even find tires with bigger outer diameter suitable for 6x6,0 Groove wheels. I see 17.5/625-6 Retread ($100) and the same size Mishelin ($349). As I understand second digit 625 means 6.25 disc width. Van?s supplies 6.0. Is quarter an inch important in this case?
Should I ask Groove?
Unlike simple and straightforward automotive tires aviation tires specification is more confused.
Finish kit is ordered but not shipped yet. It is not too late to delete wheels & brakes and try to fit bigger wheels compatible with Van?s main legs?
Do I miss anything simple and evident?

Thanks for any advice.

And of course I understand that I won't be able to use stock fairing.

Why do you want bigger tires?

Carl, just flexability. Soft field, gras, etc...

The 10 uses 15/6x6 tires. These are a special,reduced diameter tire. The std 6x6.00 tire will have a larger diameter with a similar weight rating. Width should be similar. Obviously, they will not fit the wheel pants without modifications, if at all.

I installed larger tires on my 14A and noticed quite a difference on soft field. The 14 uses 5 inch wheels.

Someone got measurements?
Goodyear charts show 15x6.0-6 at 14.5" diameter inflated (there is a higher speed rated tire at 15.2" also listed). 6.0-6 listed at 17.5" inflated.
Assuming the 120mph rated tire is Vans stock, the space above the tire inside the wheelpant would have to accomodate an extra 1.5" radius to fit a 6.0-6.
Also the hangar door would have to safely clear the tail which would now be about 5" taller.

Regarding the -7, I switched to the 380x150-5 tires and am very pleased with the overall results. Minor enlargement of the wheel pant openings, no noticeable change in speed, much better soft field footprint and better hard surface ground handling. No Brainer upgrade!

Don't have time to re-research it right now but I think the Desser Monster retread tires in 15/6x6 are a somewhat larger OD, and I plan on vertically spacing my wheel pants for same, while starting out with the Chinese tires in the kit. Once those are worn, I plan to replace with the Monsters for the hopeful increase in soft field sure-footedness since I will fly 95% off grass, here at home.

Am I correct?

Bill,

I talked with Desser at OSH this year (and bought my tires at a show discount). They apparently don't make the "Monster Retreads" for the 10-sized tires. The do make retreads (which is what I bought), but they are not the thicker "Monster " retreads, like they make for the other Vans Aircraft tire sizes. In other words, the thickness of the retreaded rubber is not thicker than the spec calls for. I've still heard that the retreads hold up better and longer than brand new, for some reason, so that's what I bought. They were also cheaper than new. Go figure!

I fly off grass and love my bigger tires.
