The sale actually runs 2 days but the bigger michelin rebate ends 6/8 so today only.
The deal I looked at was $110 rebate on michelin, $100 instant savings (many are $80) and $40 rebate for using their CC.
Its on discounttiredirect.com but local discount tire/america's tire will price match.
Tomorrow the michelin rebate falls to $70 from $110 but most other deals are unaffected and will work tomorrow
(if you hate michelin for example)
For an example the Pilot sport 3 A/S 195/55r16 144.00/ea
-80 instant saving
-40 Discount tire CC MIR
$346 for 4
of course that is excluding tax, mounting balancing, state fees.
Shipping is included but I would price match at local DT https://www.discounttiredirect.com/promotions/flash-sale
