Rins: Getting stuck behind Petrucci cost me win chance

Rins ran in the battle for second with Petrucci for much of the Catalan Grand Prix, but was unable to keep the Ducati behind when he tried to pass him at mid-distance with an aggressive Turn 4 move.

He almost collided with Petrucci under braking for Turn 1 late on while trying to re-pass, and dropped to sixth as a result, before recovering to fourth at the chequered flag.

Rins says his tyres overheated while following Petrucci, which caused him issues under braking, and ultimately stopped him from closing the gap to eventual winner Marc Marquez.

“Looking at the data, can be [the case], because behind him the [front tyre] pressure went up, and to reduce the pressure it's difficult,” Rins said when asked by Motorsport.com if clearing Petrucci would have allowed him to close in on Marquez.

The Austin race winner added: “I was expecting to go a little bit faster, but on Sunday the engineers analyse a lot the tyres, the bike.

“Sincerely, behind Petrucci our bike was fully hot. The tyre pressure went up immediately. And maybe for this reason we were struggling a lot of the brakes, and also on turning.”

Rins was almost thrown from his Suzuki at Turn 3 on the fourth lap, and blamed this on a “strange” problem with right shoulder of his medium rear tyre, which at lean angle made the bike “uncontrollable”.

“I was faster than Petrucci going in [to the turns], but then on the acceleration we lose a lot [because of] the tyre.

When I overtook him I tried to push two laps, but was impossible to open a small gap. During all the weekend we were very strong on the last sector and during the race we lose a lot of time there.

“Until I overtook Petrucci on the fourth corner, he did one step more. He was able to follow me.

“[It] was difficult for me because, for example, at the first corner, braking straight was good, but when I was leaning the bike the rear was uncontrollable. I was so close to crashing there.”
