What tire pressure after market rims? - after market audi tt rims
I have a 225 HP Audi TT that comes with 225/45/17 and recommended 33psi rear and 30psi front. Now I have 235/40/18. I Should the tire pressure as the place that it has recommended, or the pressure must be higher, because I have to say. Since about 40 psi.

Ready for a quick course in the intricacies of the plus-size? Well, let's start with the basics.
ReplyDeleteThe right way to express the size of your tires OEM Audi, is a function of the year or 225/45R17 91Y "or" 225/45R17 90Y "and not" 225/45/17 ". All information about the tire size is important, not only the physical dimensions, especially when we have more than size. You'll see why in a moment.
If you have more size there are two essential criteria that you want to meet.
1. Replacement tires must be as close as possible to total diameter of the OEM tire size.
2. Replacement tires must meet the ability or the viability of the OEM tires to more than the recommended inflation pressure. The air flow can keep the tires can handle determines the amount of cargo that. At one point, more pressure plus shipping. The tires of different sizes have internal air volumes and sometimes change in the size of the air pressure must increase to compensate. There are tablesdo specifically for you. Luckily for you, a team in mine. A good knowledge of the total size, not just the physical aspect is of fundamental importance.
The 17-inch wheels on your original Audi has an approximate diameter of 25.0 inches and rotates 833 times per mile in new condition. The load index of 90 or 91 depending on the year, which tells us that can carry psi at 33 of the tire a load is 1235 pounds (90) or 1268 pounds (91) respectively, or 30 psi in 1146 and € 1179 respectively ..
What are their goals.
A 91Y tire size 235/40R18 or 91W is a total approximate diameter of 25.4 cm and rotate 820-times per mile. This value is slightly larger than the OEM tires, but acceptable. A better option would be the size of the Audi was an option on these cars: 225/40R18 XL 92Y. This size has a diameter of 25.1 cm and rotates 830 times per mile - almost perfect! Anyway, since it 235 and it should run with it.
In a standard load (235/40R18 91W or 235 /40R18 91Y) have the same load index as the number of tires OEM = 91 This means that at 33 psi this tire carries the same load of 1268 kg to 30 bar is 1179 pounds. Therefore, there is no inflation pressure changes are necessary. You can still 33/30 without worrying at all. The same happens even if you have the additional burden (often referred to as "enhanced") 95W XL size 235/40R18 tires. 33/30 psi in the load is the same.
Simple is not it?
PS
Vomit Stangman myth is widespread, but totally unfounded. Besides the size and the correct tire pressure is very scientific and thoroughly presented by the Rubber Manufacturers Association (RMA)
is necessary to side with the new tires for the check of his psi max. If the recommended change in the tire and wheel size, the pressure created by the manufacturers from the window. If your tires say 50psi max, then you should run around 40 psi cold for a mix of comfort and fuel economy
ReplyDeleteCorrect is based on the tire pressure first. We must then consider what the car is used, it is only one driver every day, I would get the pressure on the tire dealer as recommended.

ReplyDeleteI stayed was the recommendation of Audi and if additional air intakes to no more than 2 pounds.
