Although many in this forum have several bikes, one each for a particular ride, do any of you just have one beater bike bike (snow, gopher run to store) and one high dollar bike ... but have more than one set of wheels/tires for the high dollar bike?

One reason I'm targeting a Trek Pilot is that is appears to be a happy medium between comfort and road-efficiency. The wheel/tire set that comes with the bike would be great for club rides, but would the following [Pilot 5.9] combination be practical for metroparks or MUPs?
Wheels = Bontrager Race X Lite (too thin for traction in a park?)
Tires = Bontrager Race X Lite, 700 x 23c, folding (too delicate for park riding?)

Do any of you have more than one set of wheels/tires for your high dollar bike ... one for parks & MUPs ... one for club rides/century ride ... and is this a realistic approach for trying to have the "best of both [off-road & road] worlds"? If this is a realistic approach, could you recommend a good wheel/tire set for the Pilot 5.9, for doing rides in metroparks and MUPs?

I run two sets. My training set is Shimano RSX hubs laced to Mavic CXP 22 rims with 36 spokes each. My racing/event set is Shimano 600 hubs laced to Mavic Open Pro rims with 32 spokes. The bike never leaves pavement. The training set is always used if I'm riding the bike paths on Hilton Head Island, and the racing/event set gets time out on the open roads of Lady's Island. There is one event up in Darlington County I use the training set on, as the roads aren't that great.
