I don't have experience with ER300. But I have experience with xm2 which are fitted on our WagonR vxi BS 3.I brought XM2 for comparison here because they are similar to ER300. Both ER300(Manza size) & XM2 (wagonR vxi size) are asymmetrical.
P. S.- Not all xm2 sizes are asymmetrical. Asymmetrical tires doesn't and can't decrease comfort unless down sized. Also, asymmetrical tires doesn't and can't decrease handling pleasure unless down sized
XM2 are not available in Manza OEM
size. Hence instead of xm2, ER300 (available in Manza OEM
size) can be used with same benefits.
And shall I take it that asymetrical tyres decrease the comfort but improve handling, road grip and steering response.
Asymmetrical tires of same
size when compared with same size symmetric tires, comfort levels is better with asymmetrical tires are more comfortable, but handling characteristics improve more, more than comfort characteristics.
To conclude, ER300 which are asymmetrical and available in Manza OEM
size (185 /60R15) are more comfortable and better on handling front too than B 250 /Acelere which are symmetrical and available in Manza OEM
Once you decide to go for ER 300, and if you feel that for you need more comfort than what ER300 is offering, then you have no option in manza OEM
size,hence you will have to upsize. Most suitable upsize is 195 /60R15. In this upsize you have first good option, that is ER 60. ER 60 are SYMMETRICAL, the width is 195 mm(10 mm wider than ER300, B 250, Acelere), so comfort level is better than them. But being symmetrical ER60 won't be better than ER300 (asymmetric) on handling front.
That is why I said ER300 (Asymmetrical) are driver's tires. IMO
B 250, Acelere(185 /60R15)symmetrical = +1comfort & +1 handling
ER300 (185/60R15) asymmetrical = +2 comfort & +3 handling.
ER 60 (195/60R15) =+2 comfort & +2 handling, if these ER 60 were available in asymmetrical option too then score would have been +3 comfort & +3 handling.
In that case, FE reduction could be calculated roughly as about Rs 3000 per year for an average running of 12000 km with current diesel prices. |
That is OK for the benefits like improved comfort, stability, road grip and steering response.
Yes, I agree.
@jp, IMHO, it seems Autosafari is not averse to sacrifice someFE for other bene fits.

Manza ichelin xm2 are designed to make the tires sidewall cut resistant. But they are available only in 185 /65
R15. Given the Autosafari 'S speeds, and abilities to cover thousands of km within a week, I won't advise him to go for this size as high speed cornering
would be a pain for him.
