[DeTomaso] 335/35/17 versus 315/35/17 rear tires

[Forest Majors]

Dan,

My experience with the Sumitomo HTR Z tires was not good. I ran them on an Audi A6 4.2 sedan. Had tread separation on two tires - both replaced. Then the third tire developed a huge bulge after hitting a normal "New England" chuck hole. That was it - a virtually new set of Sumitomo tires went in the trash can.

The problem was that  I really liked the tires. Great price, great profile on that Audi, very sticky and perfect high speed summer tires. Except that damn things were defective. They might be great on a lighter car with perfect roads - but I would not recommend them.

  My white Pantera needs rear tires.  It currently has 335/35/17 Michelins.
  Looks like the choices for non-race tires are:

   Michelin Pilot Sport PS2
   $443 each tirerack.com
   220 treadwear rating
   Y speed rating
   Treadepot.com has PS2's listed for $447 with free shipping

   Pirelli PZero System
   $480 each  tirerack.com
   140 treadwear rating
   Y speed rating
   Treadepot.com has Pzeros listed for $412 with free shipping

   Dunlop Sport 8000
   335/35ZR17
   $487 each  www.1010tires.com
   200 treadwear rating

  The Michelin and Pirelli are listed as "Max Performance Summer" tires on
  tireracck's site with a warning they are "not intended to be driven in
  near-freezing temperatures, through snow or on ice".  I prefer the
  335/35/17 size but if I drop to a 315/35/17 size, there are several more
  less expensive tires to choose from:

   Goodyear Eagle F1 GS-D3
   315/35/17
   Y speed rating
   280 tread wear rating
   $292.00 (Back Order)

   Dunlop SP Sport 8000
   315/35ZR17
   W Speed Rating
   Treadwear: 200
   $316.00 (each) Back Order

   Sumitomo HTR Z
   315/35ZR17
   Treadwear: 160
   $99.00 (each) In Stock

  Another interesting tire:

   Vredestein Ultrac Sessanta
   315/35ZR17
   280 tread wear rating
   Y speed rating
   $169 each at www.performanceplustire.com

  The Sessantas are supposedly very quiet for a performance tire with
  excellent grip.  They have 225/45Z/17, 235/45/17 and 245/45/17 sizes
  for the front in the $130-$135 range so I could get a set of 4 for
  around $600, considerably cheaper than just a pair of 335/35/17 rear
  tires.  Anyone tried these?  I found a discussion on a Vette forum
  that was favorable:
