Can 235 tires be replaced with 255 tires?
2 Answers
It is possible to replace 235 tires with 255 tires without changing the rims, provided that the tire is marked as 8.5J (rim width). If the J value is too large or too small, it is not possible to replace 235 tires with 255 tires without changing the rims. This is because each rim width has an appropriate range of tire widths. In addition to checking the rim width, the diameter and depth of the wheel arches must also be considered when replacing 235 tires with 255 tires. The diameter difference between 255 and 235 tires should not exceed 3% to be within a reasonable range. Tire maintenance: Check the tire pressure of the vehicle, including the spare tire, every 15 days. Regularly perform wheel balancing to prevent the vehicle from pulling to one side. Inspect the tires for excessive wear once a month. If there are any foreign substances on the tires, clean them promptly. Tire usage tips: Overinflating the tires can cause the tread to bulge, leading to excessive wear in the middle area over time. Therefore, when inflating the tires, refer to the standard tire pressure specified in the vehicle's manual. Conversely, driving with underinflated tires for extended periods can cause excessive wear near the inner and outer tire shoulders.
This tire issue is something I often hear about at repair shops. Switching from 235 to 255 tires is theoretically possible, but it depends on whether the specific rim size matches. The 255 indicates a 20mm wider tread, which may exceed the original vehicle design. You need to check if the rim width is sufficient—typically, a rim width of at least 7.5 inches is required to prevent slippage. You also need to consider clearance issues. After installation, turn the steering wheel to see if the tire edges touch the wheel arches or brake discs, as this could cause significant wear. Additionally, the tire diameter may change, which could interfere with the speedometer reading. It's advisable to first measure the original vehicle space with a ruler or consult a professional shop for compatible models. While wider tires can improve cornering grip, they come with higher costs and may affect fuel efficiency. For safety, don't attempt this swap blindly. I recommend consulting a certified technician for testing to avoid additional damage to the suspension system.
