Hello,
Last replaced all 4 tires 21000 miles ago. The rears are done the fronts still have a little life. Wondering who would replace all four out of convenience, fronts are only $100 a pop.

Any thoughts?

 

How old?

Match the fronts with new rears. You don't need all four new. Unless they are 5 years old.

$100 front tires? That's super cheap.

 

Keep the fronts. But get the same brand for the rears, same brand and make even better.

 

At $100/ea....no question, replace all four.

 

They are all 3 years old, tires are Sumitomo HTR Z III. $105 fronts, $125 rears. I don’t track my car and these have been great for my purposes.

 

If you are happy with the Sumi’s then get 4.

 

yup

 

Sumitomo tires are actually pretty good and amazing value. Have had them in the past and no complaints. Now as others said, since price is quite good, do all four.

If staying with the same make and model of tire as what's on the front, there's no need to prematurely change the fronts until they're worn out. Most 997s will go through 2 sets of rears for each set of fronts, sometimes even 3 sets of rears for 1 set of fronts if doing a lot of hard accelerating.

Even though it's only $200, if you want to throw away money, I can send you my PayPal address

 

+1 why spend the money if you dont need to? There is no need to change the fronts if they only have 3 yrs on them and still have tread

 

This all assumes that your time is worth nothing. If you change all 4 at once, its one trip to the tire place.

If you change just the rears now and then the fronts when they come due, there is the incremental cost of another tire shop visit, beyond just the cost of the tires themselves.

If that added scheduling/going there is worth less than the cost of the remaining life on the tires (which isn't much if they are 5 years tires that cost $100, and are not quite but a good way used up), then sure, change them.

When I was in college, and had lots of free time, sure I'd have no issue doing just what needed doing. Now in a full adult life with lots of scheduling responsibilities, I'd pay money to combine shop visits.
