Opinion on new cobra tires

[kart49]

Has anyone ran theses tires wondering how they compare to maxxis pinks and blue performance and prepping wise.

Extremely stiff sidewall.

Like a Maxxis and a Vega has a baby....with the exception that they smell like vulcanized rubber combat boots from the Vietnam era... we’ll see how they work.

Extremely stiff sidewall.

They as stiff as a red vega

They as stiff as a red vega

Is that a question or a statement?

I'm betting a question.

Spring rate 185

Spring rate 185

Can you give us something to compare to? And how do you check that?

My guess is Intercomp spring rate tester .
https://4cycle.com/karting/threads/how-spring-rate-affects-the-chassis.20468/Waller Racing is on top of current technology .

 

[flattop1]

Spring rate 185

Unprepped I assume .
How about a Maxxis or Vega?
What do they have for spring rate ?

 

[PRC01]

Maxxis is about 180 +\- 3
Best I can check with a Vega is with 30 laps on it and is about 168

I’m picking up a set of these next week plan to run them at a track in about 3 weeks, open tire rule so I hope everyone else will be running maxxis so I can compare.

I thought everyone always said yellow vegas had stiffer sidewalls than maxxis?

I'd say that was Burris, Vegas stiffer than Burris but not Maxxis.

 

[PRC01]

Like I said, the Vega has laps on it so not sure how much it dropped it. Next time I mount a new one I’ll check it.

Has anybody had a chance to check these with a durometer?
