What is the tire specification for the Excelle?

[OAxel]

The Excelle 1.6LX series and 1.6LE series differ in wheel rims. The former has a tire specification of 185/65R14, while the latter is 195/55R15. Below is relevant information: 1. The tire specification model size is expressed in millimeters for the section width and the percentage of the aspect ratio. This is followed by: tire type code, rim diameter (in inches), load index (permissible load-bearing mass code), and permissible vehicle speed code. For example, a tire specification could be 195/55/R1685V. 2. Tires are circular elastic rubber products assembled on various vehicles or machinery for rolling contact with the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, achieving contact with the road surface, and ensuring the vehicle's driving performance.

I've been driving an old Buick Excelle for six years, which originally came with 195/55 R15 tires. In this specification, the first number 195 indicates the tread width, 55 is the aspect ratio, and R15 means 15-inch wheels. Last week, I just got new tires, still choosing the same specification, Michelin Primacy 4, which offers good comfort and quiet performance. Remind everyone to pay attention to the production date when changing tires. There is a four-digit DOT code on the tire sidewall, for example, 1523 means the 15th week of 2023. It's best to replace two front tires or all four at once to ensure even grip. By the way, the spare tire is full-size but tends to age easily when stored in the trunk's spare tire well, so it's recommended to check the spare tire pressure annually.

Yesterday, I helped my neighbor inspect his 2015 Excelle. The tire specifications were clearly labeled on the door frame tag on the driver's side, showing 185/65 R14 86H. The 86 is the load index, capable of bearing approximately 530 kg, and the H is the speed rating with a maximum of 210 km/h. I measured the tread depth and found it was only 1.6 mm left, which is dangerous if it goes below 1.6 mm, as it can easily skid in rainy conditions. For tire replacement, it's advisable not to go for the cheapest option. Last time, the repair shop suggested switching to 195 tire width, but it's actually unnecessary as the original factory matching is the best. Monthly tire pressure checks are essential, maintaining 2.3-2.5 bar when the tires are cold is most suitable. Insufficient tire pressure not only increases fuel consumption but also damages the tires.

Workshop records show the Excelle commonly uses two tire specifications: base models use 185/65 R14, while premium versions come with 195/55 R15. Special attention is required for the 55 aspect ratio - must slow down over speed bumps as the thin sidewall is prone to bulging. Encountered cases where owners wanted to install wider 205 tires, but the rim J-value mismatch could cause bead dislodgment during forced installation. Recommended compatible brands: budget option - Chaoyang SA37; for quietness - Continental UC6. Critical reminder: wheel balancing is mandatory after tire replacement, otherwise steering wheel vibration will occur at high speeds. Always have mechanics check the valve stems, as aged rubber components tend to develop slow leaks.
