2011 Cadillac CTS Summer Tires vs New All-Season Performance Tires

One of the highlighted New Features for the 2011 Cadillac CTS Sedan is

  • (FE5) 19″ All-Season Tire Package
  • (Q2B) P245/45R19 all season blackwall tires. Included and only available in (FE5) 19″ All-Season Tire Package.

Let’s look at exactly what that entails.  It is intriguing that RPO code FE5 was selected, since this would suggest even higher performance.

FE5 NEW! 19″ (48.3 cm) All-Season Tire Package
1 – Requires (Y42) 18″ All-Season Tire Performance Package. Includes (KB7) steering wheel mounted Paddle Shift controls. (Q2B) P245/45R19 all-season blackwall tires replace (QKE) P235/50R18 V-rated all-season blackwall tires. (PJ2) 19″ x 8.5″ polished wheels replace either (P75) 18″ x 8″ aluminum wheels with premium multi-coat painted finish or (P63) 18″ x 8″ aluminum wheels with high-polished finish. Not available with (Y43) 19″ Summer Tire Performance Package, (MN6) 6-speed manual transmission, (W2E) Recaro performance seats or (SE4) LPO, 18″ chrome wheels.

So it is an option that pushes the 3.6L DI CTS to 19″ all weather tires, and 245/45 versus 235/50 stock tires.

Y43 Performance Package, 19″ (48.3 cm) Summer Tire, includes (T4F) HID headlamps, (KB7) steering wheel mounted paddle shift controls (MX0 6-speed automatic transmission only), (T3U) fog lamps, (PJ2) 19″ x 8.5″ polished wheels, (Q0M) P245/45ZR19 Y-rated performance summer tires, (V03) performance cooling system (MX0 6-speed automatic transmission RWD only), (FE3) sport performance suspension, (G80) limited slip differential and (J55) performance brakes
1 – Model 6DP69 only. Not available with (Y42) 18″ All-Season Tire Performance Package or (FE5) 19″ All-Season Tire Package (Model 6DP69 or 6DH69).

The Summer Tire package has 245/45 tires also, but includes other performance bits as well.  So the FE5 gives the cornering advantage of the 19″ wheels and all-weather benefit of all-season tires at the expense of the ultimate performance of the Performance Package Summer Setup.  In other words, the FE5 option is a good approach to performance if you want more sport but know you will be driving in weather.
