I would like to create this thread so most can learn that brand new tires dont provide there best grip during the first thousand km depending on there rubber type(Sports,economy tires etc).
A brand new tire will provide better girp than a bald/worn out tire but many dont know that there brand new tires are not at there optimum level yet.
Giving some examples from my observations Example 1-
My i20 has stock Apollo tires ,on a decent braking scenario on highway or regular roads i use i could hear the Abs
click or kick in,Abs
kicks in when a wheel slippage is detected,so its understandable that there were minute slippage,i am very particular about tire pressure & i fill it at a local shell petrol pump cos of accuracy in there equipment.
I did not experience any change in grip until the car had finished 8000 km,now on similar or harder braking at 9000 km i notice grip has increased cos the abs
does not click much,it proves without doubt the age old fact about running in new tires. Example 2 -
Back in 2005 our friends group was crazy about Superbikes & would take them on long rides,so in preparing for one such long ride my friend decided to have the rear tire on his Yamaha R1 changed,after he got on the new tires i think same brand 195 section Michelin tires as the one before,he rode it home after riding on new tires for some 15 kms,
the drive way of his house was smooth as he drove up i saw him drifting the bike left & right.He was stunned & explained to me that the previous tires which were in decent condition had better grip & never lost so much traction.It became evident how important it is to break/run in a new tire. The Reason
Tires are comprised of many layers of rubber, steel and fabric. Due to these different components, your new tires require a break-in period to ensure that they deliver their normal ride quality and maximum performance.Why is this necessary? During the manufacturing process, tires are coated with a lubricant to prevent them from sticking to the mold. That lubricant can take up to 800 kilometers to wear off. Until that happens, the lubricant can reduce the traction of the tires, especially on wet pavement. Consequently, new tires should not be subjected to hard acceleration, cornering, or braking. Driving at or just below the legal speed limit will also allow the lubricants used during the manufacturing process to wear away. It is also important to note that your old tires probably had very little tread depth remaining when you felt it was time to replace them. As any autocrosser or racer who has tread rubber shaved off of his tires will tell you, low tread depth tires respond more quickly. Don't be surprised if your new tires are a little slower to respond (even if you use the exact same tire as before). Their new, full depth brings with it a little more tread squirm until they wear down. NOTE: Be careful whenever you explore the capabilities of your new tires. Remember that every tire requires a break-in period of 500 miles(or 1000 km atleast for our Indian market stock tires) for optimum performance.
