wife's car needs new tires.
been doing some research
we live in Mississippi so no snow.
I was looking at some all seasons.
car has only 30k+ miles and still has factory tires
BRIDGESTONE
POTENZA RE050A
Front: 225/45R19 92W
Rear: 245/40R19 98W XL


I have been looking at the
BF Goodrich g-FORCE COMP 2 A/S Tire
or the Continental Extreme Contact DWS06 Tire
the bfg's are cheaper but only by about $100 a set
some reviews talk about a high road noise which I don't really want


I see a pretty good deal on DWS06 255/40R19's that I could use in the rear and put 245/40R19 on the front.
actually the rear POTENZA RE050A 245/40R19 98W XL have much more wear left on them and I could just put these on the front.
these are W rated while the DWS06 are Y and tire rack told me it might be better not the have 2 different ratings? any truth?
I would really rather buy a set of 2 for now as the rear probably have at least another 10k left on them.


I would like to try to keep the gas mileage about the same

I was also looking at going to up size and see that
Front: 245/40R19
Rear: 275/35R19
are the most common replacements.


This is for the wife so although I might like the look of the wider tires, I don't want to make it harder to steer or drive.
Any suggestions?
Anybody runs these brands (they are fairly new replacing older series w close to the same name) ?
Anybody done the upsize and can tell me what they think?


Also since we are in the back woods state, I was looking at ordering on line.
tire buyer has best price, but reviews are either 1's or 5's
amazon is close to tire rack, gut tire rack offers free road hazard which may make them the most logical choice
fyi for those looking, most offer cash back sites like ebates to save 4 - 6%


thanks.
