Hey Everyone,
I stumbled across this thread when i was looking for suggestions for new tires for my 2005 Winnebago Rialta.
About four months ago i was in a similar situation - i needed new tires before a cross country camping trip. I searched for days for replacements for the Continental VanCo tires but it seems that they have discontinued production on those tires.
I noticed a few people saying that Nokian made a nice tire called the WR-C Van tire. I hadn't ever heard of Nokian before so i gave the guys at TiresByWeb.com a call (only retailer online i could find). They turned out to be very familiar with the Rialta and its tire sizes/load index requirements. All in all they were very helpful, and best of all they had the tires in stock in the 195/215 sizes. Although i decided to take some advice from this thread and do the 215's all the way around. They arrived in about three days, i was very impressed with the quickness of the whole transaction.
It's been about three months since i've had the tires installed and i am very pleased. I haven't noticed any rubbing issues at all in the front. The noise level of the Nokians are very similar to the Vanco's, but the handling is much more responsive.
All in all, i would definitely recommend going with the Nokians.
