Owners report tread and belt separation on multiple tire brands fitted to 2008 F-250s, typically occurring between 12,000 and 44,000 miles despite regular maintenance and inflation. Continental ContiTrac LT275/70R18 and LT275/65R18 appear most frequently, with separations happening at highway speeds, sometimes causing violent shaking, rim damage, and loss of vehicle control. BF Goodrich Rugged Terrain T/A 20-inch tires, Federal Couragia models, Cooper Discoverer AT3, and Goodyear Wrangler AT/S also show separation failures. Some owners replaced two tires from a set only to have the other two fail shortly after, suggesting batch defects. Multiple owners note Continental has recalls on certain LT275/70R18 DOT codes but their tires fell outside the recall window or had different DOT codes, leaving them unprotected. Tire pressure monitoring system (TPMS) faults are reported separately—one owner experienced six false low-pressure alarms within 18 months and sensor faults even after dealer sensor training and replacement. One owner received a spare tire 2 inches smaller than road tires. Cracking around tread-to-carcass attachment and multiple microscopic leaks in tread are also documented. Manufacturers typically deny warranty claims, offer only prorated replacements, or claim tires fall outside recall coverage.
Failure modes owners describe
Tread Separation (ContiTrac LT275/70R18)
Tread and belt separation occurring at highway speeds on Continental ContiTrac tires, often with violent shaking and no prior warning signs until separation is advanced. Multiple cases reported with tires outside manufacturer's recall window despite matching defect symptoms.
When: 12,000–44,000 miles; some cases under 30,000 miles
Symptoms owners cite: Violent shaking at 50–70 mph; Tread peeling off in chunks; Bulging on sidewall prior to separation; Continued vibration after discovery
Codes mentioned: DOT P5B9 1VUB (non-recalled code), DOT A3B9 479B (replacement tire), NHTSA Campaign 11T002000 (ContiTrac LT275/70R18 recall—excludes some DOT codes)
Repairs/costs cited: Tire replacement required; one owner replaced two tires from set only to have remaining two fail. Damage to rims and fenders reported. No warranty coverage offered outside recall DOT codes.
Recalls/TSBs owners mention: Continental voluntary recall for ContiTrac LT275/70R18 on certain DOT codes only; tires outside recall codes denied warranty. Manufacturer offered to replace only failed tire, not entire set.
Tread Separation (ContiTrac LT275/65R18)
Belt and tread separation on Continental ContiTrac LT275/65R18, with shifted belt and tread peeling. Owners report symptoms matching those of recalled tires but claiming different tire sizes fall outside recall scope.
When: 24,554–43,910 miles on original equipment
Symptoms owners cite: Abnormal vibration indicating separation; Shifted belt visible inside tire; Tread peeling off during inspection; 9/32" tread depth remaining at failure

Repairs/costs cited: One tire replaced under warranty at 24,554 miles; owner forced to purchase replacement tires for remaining two tires with no warranty coverage. No cost estimates provided.
Recalls/TSBs owners mention: Continental acknowledges ongoing recall for LT275/70R18 but claims LT275/65R18 outside scope. Owner reports defect matches listed recall defects but believes additional tire sizes warrant investigation.
Tread Separation (BF Goodrich Rugged Terrain T/A 20-inch)
Tread failure and complete tire failure on BF Goodrich Rugged Terrain T/A 20-inch tires at relatively low mileage. Recall exists for this tire model but not for 20-inch size, leaving owners unprotected.
When: 37,667 miles on tires purchased new 7/23/12; failures at 7/5/15 and 8/21/15
Symptoms owners cite: Tread peeling off while driving I-75; Complete tire failure while on I-95; No prior warning signs noted
Codes mentioned: BF Goodrich Rugged Terrain T/A (20-inch—no recall coverage)
Repairs/costs cited: Passenger-side rear tire replaced under tread warranty; driver-side rear failure caused ~$3,000 damage. Tires regularly maintained, rotated, and properly inflated per owner documentation.
Recalls/TSBs owners mention: Recall exists for BF Goodrich Rugged Terrain T/A but only in sizes outside 20-inch; owner requested recall investigation for 20-inch size but status unknown.
Tread Separation (BF Goodrich Commercial T/A LT275/70R18E1)
Tread separation on original BF Goodrich Commercial T/A tires purchased November 2010, with two of four tires failing before 30,000 miles and evidence suggesting remaining two likely to fail.
When: Less than 30,000 miles; failures ~3,000 miles apart
Symptoms owners cite: Tread separation discovered before catastrophic failure; No reported vibration or prior warning
Codes mentioned: LT275/70R18E1 BF Goodrich Commercial T/A
Repairs/costs cited: Two tires replaced; owner proactively replaced remaining two tires despite no separation signs. Tire service company denied warranty proration for tires not yet failed. No cost breakdown provided.
Recalls/TSBs owners mention: Manufacturer recalled similar tires; offered only proration, not full replacement set. Owner rejected response as inadequate given manufacturing defect and existing recall.
Tread Separation (Federal Couragia A/T and MT)
Belt and tread separation on Federal Couragia tire models, including both A/T and MT lines, with repeated failures across two consecutive tire purchases.
When: First set failed at ~12,000 miles (14,000 miles for another owner); second set failed after 8 months
Symptoms owners cite: Tread separation at 65 mph causing loss of control and crash into concrete median; Steel belt separation after 8–10 months in service
Codes mentioned: Federal Couragia A/T LT245/75R16 120/116Q, Federal Couragia MT 35X12.50X20 (DOT4113 on second set)

Recalls/TSBs owners mention: Federal will not respond to owner compensation requests or warranty claims.
Tread Separation (Cooper Discoverer AT3 and other aftermarket)
Complete tread separation on Cooper Discoverer AT3 tires where entire tread separated in one piece, similar to a retread failure, despite excellent remaining tread depth.

Recalls/TSBs owners mention: <UNKNOWN>
Tire Pressure Monitoring System (TPMS) False Alarms
TPMS malfunction generating false low-pressure warnings despite tires being properly inflated and within 2 PSI of each other. Recurring alarms following tire rotation and sensor training, with problem occurring only at interstate speeds.
When: Six alarms within 18 months; problem recurred after tire rotation
Symptoms owners cite: False low-pressure alarm despite verified correct inflation; Sensor fault codes; Alarm triggered only after tire rotation and only at 65 mph on interstate over ~4 miles; No alarm during local driving
Codes mentioned: Sensor fault (unspecified code)
Repairs/costs cited: Two TPMS sensors replaced; system retraining performed at dealer. Dealer suggested nitrogen inflation and attributed problem to cell phone interference, neither of which resolved issue.
Recalls/TSBs owners mention: Ford dealer stated system was designed to function as described and no problem existed after final sensor training, despite continued false alarms.
