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.
