to all corolla owners out there
as u all know, most se saloons and altis owners have changed the original 14" tyres to 15" in order to give the car a better look.
well i have 2 SE saloons in my office and have extensively driven both. one has 15" tyres while the other has original 14" tyres. i have noticed 2 marked differences between the 2. would like share it with u all.
as u know corolla has a badr grip as it is, however the car with 15" tyres has a much more shaky grip compared to the car with 15" tyres. especially on highways the car 15" tyres does not feel sure footed and feels swayed by cross winds. the car with 14" tyres still has somewhat an acceptable grip.
the acceleration of the car with 15" tyres is definitely slower than the one with 14" tyres.
i cross-checked my findings with a technical person at toyota. he confirmed that this is the reason that toyota is not offering 15" tyres in corolla. he explained that bcz of the high-roof design, the car's centre of gravity gets affected if its fitted with 15" tyres.
