Could this be an option? The message is from one of the guys on the forum for Pantera owners, who face the same issues with tires.

Subject: [DeTomaso] V-rated 225/50 and 295/50 tires available now--at last!!!
Hi guys,
I found V-rated 225/50-15 front tires here:
http://www.maxxis.com/products/autom...il.asp?id=5457
And almost-matching 295/50-15 rear tires here:
http://www.maxxis.com/products/autom...il.asp?id=5474
The latter are listed as H-rated on the website; I've eyeballed them myself and they are in fact clearly marked as being V-rated.
The price is right too!
I'd check the markings to be sure however.
They are carried by Les Schwab tire stores in the USA.
