Runflat tires have extremely stiff sidewalls and are designed to retain their structure when pressure is low (so they can "run" while they're "flat"). That's why reducing tire pressure on an RFT tire isn't going to do much to improve your grip.
In general, the reason one lowers tire pressure for the purposes of the drag strip is to induce more "give" in the tires. Less pressure in the tire means less rigidity of the sidewall, which allows the tire to flex more under load. This additional flex lets the rubber stay in place just a bit longer, and that translates to more grip. |
