Discount Tire/Americas Tire has always matched up tires on all of my cars for the last 30 some years.
Any tires will work, but a few small points. And are generalizations and your specific tire may be an exception, but after four years in the industry building tires and 35 years wearing them out this is some additional info for you to consider.
The T rating or H/V/W/Z are speed ratings and the construction is the overriding factor to consider
W, Y and Z are over kill for the Avalon.
S - Up to 112 mph
T - Up to 118 mph
U - Up to 124 mph
H - Up to 130 mph
V - Up to 149 mph
W - Up to 168 mph
Y - Up to 186 mph
Z - 149 mph and over
The speed limit is based on design limit for destruction. eg. "When will the tires delaminate or shred if pushed past the rated limit?
The belts/plies tread are wrapped and reinforced and designed for handling.
Radials will roll easier that bias ply. Weight of the car will wear out the tires quickly and as you know the AV is not a lightweight.
Generally the higher speed ratings also have a proportionally softer rubber compound
on the tread. This accounts for softness and stickiness and ease of wear.
(When you find a W/Y/Z tire with mileage warranty, it is rare. They wear out quicker because they are generally softer rubber compounds.
The belts/plys are the stiffening factor.
The tires will have markings for side plies. Aramid or Nylon normally. The Steel is usually on the tread. The side of the tire will also be indicate 1 2 or 3 belts/plys.
If you can find a tire store you can find some tire samples and feel the sidewalls and check their flexibility while they are off the rim.
Compare a Goodyear/Pirelli/Bridgestone Z or W rated tire and then a S/T/H and you'll see immediately the difference.
You probably should use the feel of the tire off the rim as a factor.
The plus up for V is that the sidewalls are built to give a little more to keep the full tread on the contact surface. and they are stickyer.
I would avoid the T and minimum H.
If price is a big factor, consider that you can get 40,000 miles on most tires. Some claim 80,000 now.
Typically a 4 year tire. At that point the exterior rubber is starting to degrade.
And it will get harder/harsher ride and lack of flex.
if you buy $80-100 tires or $150 the difference of the set of 4 is $200 for the set?
That's $50 a year for great tires or tires that might be...
I'll be trying to find a Yokohama YK 580 or Michelin Premier V rated tire.
Had the Yoko's on two heavy Volvos and they are nice.
Discount tire will trade out any tires in 30 days if you don't like them...
Nothing in Maryland that I can find.
