Have been on these tires for a week thanks to @Tianmo. Had 10000km on it when he passed them to me. These tires are comfortable and not too noisy IMO. My wife did notice the difference and mentioned that the ride is not as harsh even though I pump higher pressure than my previous tires.

hello bros,

 

i'm rather new here and new to tyres. Always keen to read in this forum for more knowledge.

 

When you guys say ''better grip'', how do you actually test this?

Hard cornering? At what speed?

 

I'm currently using bridgestone gr100, a comfort tyre. I did cornering at 80km/h. Thought it feel ok. Not sure what i should be feeling.

At stationary, put gear to N. Step on accelerator till 5,000rpm. Left foot on brake, shift immediately to D. Depress accelerator to redline.

 

- If tyre screech or wheel spin, no good grip.

 

- If no wheel spin and power away, very good grip.

Depends on what car. I tried it a chevy Cruze. Doesn't work. You need to leave it in D, left foot on the brakes and floor the accelerator. And then let go.

Almost any fwd/rwd car can make the wheels spin if you do this. Lol.

Then lower the rpm by decrements of 1,000 rpm till no tyre screeching or wheel spin. E.g if 5,000 rpm, tyre screeching, lower rpm to 4,000 rpm.

 

The higher the rpm, no tyre screeching = good gripping tyres. :D

 

 

 

This is the most systematic way to test for "good grip". [laugh]

Finish testing already, you'll know which tires got better grip but gearbox gone.  [laugh]

how much it costs for 245/45R17 per tyre? can last how long?

I think around $130. I changed mine 215/55/R17 last year for $130.
