Is the 22-inch wheel hub really a problem?
The 22-inch caliper is really nice, and it's probably cool at high speed. But what if I want to go to Tibet? Change it to 18 inch? No problem, it won't cost much to buy four more, but the brake discs and calipers should also be replaced. This is embarrassing. . . After coming back from Tibet, I will still use the 22-inch TV. /kloc-how about 0/8 inch brake group? There are two 20-inch AT tires available for reservation in Hutu. One is the universal grabber 5255/50r 20. The tire size is exactly the same as that of Tang standard (not upgraded) and can be replaced directly. The other is the universal tire gripper 5255/55R20. In Bitang, the diameter of 265/40R22 installed on the top of this tire increased by 17.7mm, but it did not exceed 3%. The radius is increased by 8.85 mm, so it should not rub against the lining. The advantage is that the tire becomes thicker, and the ground clearance increases by 8.85 mm, which improves the passability of vehicles. It should be good to go to Tibet. Look at the previous rider's post, the 20-inch wheel hub should be able to be fitted with Brebo 6 piston calipers, so the braking system is good. If BYD doesn't force the upgrade of tires, I will need the standard tire wheel hub Brebo 6 piston caliper (front wheel), so before I go on the road, I just need to change the tires into AT tires, and nothing else needs to be moved, which saves trouble and money. The original tire pressure monitoring module is installed on a 20-inch wheel hub and can be used directly without moving. More extreme, buy a 20-inch wheel tire and install a tire pressure detection module as a spare tire. The flattening rate of 50 and 55 is not too high. If you choose a flat rate of 60, you may have to change to 18 inch tires. There are more tires to choose from. However, if the hub of 18 inch is to be replaced, it is a problem whether the Brebo 6 piston caliper can be put down. 18 inch wheel hub may not be in the factory configuration table of Tang DM. AT tires with flat ratios of 50 and 55 can always walk more roads than tires with flat ratios of 40. Tang DM has strong power. If he can't go up the mountain, the power reserve will be redundant. Racing on paved roads is also illegal. Only this disagrees. . In fact, most consumers are like me. For example, mobile phones like to look like apples. For example, cars need to be big and have many seats, tires need to be thin and wheels need to be big. . All kinds of irrational needs anyway. In essence, it is estimated that the car is still not regarded as a simple tool. I changed it with someone else's 20-inch all-wheel tire caliper. When I came back, I gave him a new tire, and then I changed it back. He also used 22-inch tire calipers for a few days. I haven't seen 20 wheels and tires yet, and 4S stores are all 22 exhibition cars. Look at the wheel hub to know if you can put down the caliper and brake disc. The inner diameter is estimated to be 508 mm for 20 inches and 405 mm for large brake discs. The key point is to see how much the hub ET is. I looked it up casually on the Internet, and the wheel tire size in the green paper of the DMV may not be easy to change. If the original factory certificate states that there are two wheel configurations, I don't know if it will work. It's probably enough to deal with the dmv. Renting a car is not very convenient either. I went to Tibet a few years ago, but I didn't book a car rental in Lhasa, so I had to rent a car to take the driver. In addition, buying a hybrid car is also attracted by Tang's mobile power station function. It is inconvenient to use electricity for fuel vehicles, and it may not be able to drive pressure cookers and oxygen machines. Gas stoves and oil stoves may not be needed in Tibet and Xinjiang, so electricity is the only reliable energy source. The Sichuan-Tibet line entered Tibet last year, and it was basically easy to get on the road. You can easily see hundreds of roads. Only the last 3 18 line has come back for dozens of kilometers, which is not good, but the car can pass carefully. In fact, manufacturers can come up with different solutions, instead of 22 big wheels, add a few kilowatt hours, so that BYD can sell things thinner than its own production, far more than giving big wheels @20 19.
