Hi,
I'm considering changing the tires on my Model 3.
I don't really understand the differences between homologated and non homologated tires (except for the price), so I'm trying to determine their impact on my tesla with data from the internet, community and calculations shared by one of my friends who owns a Model X (performance), and worked for a contractor involved with chassis dynamics!
I think this forum is the best place to have extra informations and support from community.
Here is my reflexion:
- 2.7s from 0 to 60 mph:
My friend (Model X owener) told me
"On a very 1st order basis , you could assume for every 5% reduction in dry grip between tires, you would add +0.2 sec to the 0-60mph time. "
"For MDL X, the highest dry grip tire is the Michelin PS4S which is 7% higher in grip than the lowest grip OE tire which is the Pirelli, no data for non homologated tire"
- 305 miles of range –
*from my research and calculations
As a assumption, we can say that for every 1 kg/ton in tire rolling resistance, you will lose approximately 3-4% in vehicle range.
*My friend told me:
"On MDL X the best to worst rolling resistance within the OE tires (the best is Conti at 7.7, worst is Good Year at 10.7) could be around 3 kg/ton so maybe it could have an impact on range around 10% (around 30 miles). Average aftermarket tires wouldn't be much worse than the Good Year I guess."
For Model X, if it's true, I think the performance loss is amazing (especially for range)
All this data is for Model X and I'd like the same thing for Model 3.
Has anyone already evaluated tire performance for the Model 3?
Another missing element is the noise difference (decibels). Does anyone know about it??
thanks for you help
