Which number in the tire size determines the profile of the tire.and is the smaller the number the lower profile
Depends on why you want to get a CAI. For performance? If so, they are all the same, don't do much and uses MORE fuel. For looks and sound, one is just as good as the other. Myself I like the CAI that the car manufacturer put on the car, with the design of a group of automotive engineers. Don't believe the hype.
kind of first is how high second how wide. last is wheel size you cant change the size by much with out hitting fenders or something not rubbing some where. what bike and year and what your plans are could have help
Here is an easy example: 120/90-18 120120mm wide / 9090% of width is the profile(90% of 120mm heigth) -1818inch rim. A 120/80-18 would be the same width (120mm)but lower profile since it's aspect ratio is only 80% of the width instead of 90%
Depends on how (which system) is used to size tyres. With old inch designation (EX 28X4.00X18) the first number is the OD of the tyre (from this subtract the ID or wheel size then divide by two,now figure the percentage of the width and this is aspect ratio) Used on older bikes through about 1940. Some Coker MC tyres still use this, so do some LT and SUV tyres. With newer inch designation (EX 5.10H16 4pr) the aspect ratio is normally 90% (the ply rating is not always added) Used on most Anglo and American bikes. With alphabetical (alphanumeric) designation (EX MT90-16 B) the number following alphas is the aspect ratio in percentage. Used on most Euro bikes. With SI (although it is incorrect this is usually refered to as metric) designation (EX 130/90-16 67 H) it is the number following the / Once used on only Jap bikes, has now become common on all newer bikes including HD
For the best answers, search on this site shorturl.im/avDuF Pretty and shiney. Also. Good way to lighten your wallet and help your fuel MPG by driving around with a lighter load. Other then thatLook where the source of the AIR is.the GREAT one designed SPECIFICALY for your truck by Ford takes the COOL outside air through your fender well Most likely the pretty one takes the HOT air from inside your engine compartment? Go back to your HS science class. What transmits heat to the Air inside the intake better The plastic (insulating) CAI that ford installed in your engine after spending Lots of money designing it so it works the best under all normal driving conditions, or the fancy ALUMINUM (Al is a GREAT conductor of heat) one from Spectre??? If you are doing it for preformance why be so wimpy with just a new HAI Go big or go home if you are going to race it. Ever drive though a puddle.does the Spectre one protect against water ingestion ? Hydroloc is a bad thing. Also if you in CA make SURE you get on with a CARB-EO number or that is listed as 50 state legal by the Mfg.otherwise you will fail your next Smog Check.
