"At the moment, we can't make any predictions, because no one has tried them and we don't know what and how many benefits they can bring, apart from trusting in the fact that it won't be dangerous to race."
But Hamilton, who lost the race lead in Britain after his left-rear tire dramatically exploded on the eighth lap of the race, warned: "I think it's still a concern and something where we need to see how it goes."
The fall-out from the British race means there will be regulated in-season tire testing as well as plans to introduce further testing next January.
In June, Pirelli and Mercedes were reprimanded at an FIA hearing for organizing a three-day tire test in May.
The German team's "secret" test still riles their rivals -- especially as they have since won races in Monaco and Britain -- but the shocking tire explosions at Silverstone underlined the need for Pirelli to find a legitimate solution to the tire failures.
Pirelli had wanted to introduce a new tire construction at the Canadian Grand Prix in June but failed to get all the teams to agree to the plan at a meeting in Monaco.
A spate of worryingly delaminations -- where the tire layers separate -- earlier in the season had led to concerns the tires were not safe.
When Pirelli took over from Bridgestone as F1's official tire supplier in 2011, the rubber was deliberately designed to be less durable so that teams would take more pit stops and the racing would be more unpredictable.
But subsequent changes to the construction of the 2013 tire, based on the same principles, have now provoked not just unpredictability but chaos on the track.
The Italian company now hopes the introduction of new tires and an agreement to monitor and test the tires throughout the season, with the cooperation of the teams and the sport's governing body, will put an end to the problems.
The Italian company are close to agreeing a new deal to continue as F1's tire supplier when its current contract runs out at the end of the season.
Pirelli say they now just need to secure agreement from some of the teams.
Being F1's tire supplier is an expensive business with Pirelli effectively paying to supply tires to the F1 grid in a negotiated deal which also includes track-side advertising.
The teams pay a small contribution towards the rubber but the bulk of the bill for the season's 36,000 spheres of rubber is picked up by the tire supplier.
"It's not cheap," said Hembery. "I'm sure there are quite a few teams who don't have our overall budget to be in F1."
The smallest teams on the grid still spend $52m a year running their F1 teams.
"It's a lot of money isn't it?" Hembery said ruefully.
