Tire size: P 235/45 R 18 While I was driving home from work my steering started feeling a little shaky. My commute is 6.5 miles. I thought it felt a little weird about 2-3 miles in and I called my boyfriend to meet me when I got home because I could tell something was off, but my tire pressure was fine.

What stands out
Tires accounts for 24% of all owner complaints filed against this vehicle, across 5 categories tracked.
The failure pattern owners describe
Owners of 2025 Kia K5s consistently report Pirelli P Zero All Season tires (235/45 R18) failing with sidewall bubbles and blowouts at very low mileage. The bubbles appear on both front and rear tires with no apparent cause—many owners deny hitting potholes or debris. One owner's tire separated at the tread with exposed cords at 6,800 miles; another experienced a violent blowout that startled bystanders. Several report three or more failures per vehicle within the first year, with replacement tires also failing quickly. One owner's newly replaced tire went flat within 5 miles of leaving the dealership.
Owners consistently report dealership blame for impact damage, but one service technician allegedly admitted this is a "known issue" with this tire on the K5. Pirelli warranty claims are refused or ignored; one owner reported Pirelli refusing to provide supervisors or callbacks. Road-hazard coverage is not offered by Kia with the standard tire package, leaving owners to pay out-of-pocket or argue with dealership coverage. One owner replaced all four tires with Goodyear all-season tires and reported an immediate improvement. The failures present a genuine blowout risk, and owners express alarm that no recall or extended warranty exists to address the pattern.
Failure modes owners describe
Sidewall bubbles (bulges)
Multiple owners report bubbles or bulges developing on the sidewalls of Pirelli P Zero All Season tires under normal driving conditions. These bubbles appear on both front and rear tires and are discovered at relatively low mileage. Owners report being told by dealerships that impact damage (potholes, bumps) caused the bubbles, but many deny hitting anything unusual. The bubbles present a serious blowout risk and are not covered under Pirelli warranty.
When: 1,400–7,300 miles; one case at 200 miles
Symptoms owners cite: Visible bubble or bulge on tire sidewall; Passenger/driver reports bubble on exterior or interior of sidewall; No prior TPMS warning in most cases; Tire pressure reportedly normal before failure detection
Repairs/costs cited: Dealership replacement under dealership warranty or road-hazard coverage; Pirelli warranty refused to cover; owners charged for TPMS sensor replacement in one case; one owner replaced all four tires with Goodyear after repeated failures
Recalls/TSBs owners mention: Pirelli warranty refused to process claims in multiple cases; one owner reported Pirelli instructing dealership to inspect tires but indicating issue likely not covered; Kia dealership warranty coverage inconsistent across locations
Tire blowouts and separation
Several owners experienced sudden, violent tire failures including complete blowouts and tread separation at low mileage. One tire separated at the tread with cords exposed. Another blew out suddenly while the owner was driving at an undisclosed speed, and a third blew out audibly after 11,400 miles. These failures occurred without prior warning in most cases despite tire pressure being normal.
When: Less than 6,800 miles (first failure); 700 miles; 11,400 miles on tires rated for 30k miles
Symptoms owners cite: Shaking/vibration in steering (escalating to violent shaking); Tread separation with visible cords; Sudden audible blowout; Tire went flat immediately after small impact (holes/bumps in road); TPMS warning light came on after failure
Repairs/costs cited: Replacement under dealership pro-care policy; one owner paid for TPMS sensor out of pocket; one owner replaced all four tires independently with Goodyear and pursued reimbursement from dealership
Recalls/TSBs owners mention: Pirelli refused to process warranty claim; dealership initially blamed owner for debris/impact; dealership comp'd tire through management in one case
Multiple tire failures on single vehicle
Multiple owners report experiencing three or more tire failures on a single new 2025 K5 within the first year or 9,000 miles. Failures include both bubbles and blowouts. One owner had four replacement attempts (original tire, two replacements, and a third replacement that failed within 5 miles). One dealer technician allegedly acknowledged this is a 'known issue with this brand of tire on the Kia K5.'
When: Distributed across first 1,450 miles (three failures) and 9,000 miles (multiple bubbles)
Symptoms owners cite: Multiple tires developing bubbles at different times; Repeated blowouts on replacement tires; Tire failure shortly after dealership replacement (within 5 miles in one case)
Repairs/costs cited: Multiple replacements at dealership; one owner paid for independent replacement with Goodyear all-season tires; one owner considering sending bill to dealership for independent replacement
Recalls/TSBs owners mention: Dealership blamed impacts/potholes for most failures; one dealer technician stated issue is known; no coordinated recall or extended warranty program mentioned by any owner
