The tyre available
The BFGoodrich Advantage Control 245/55R18 103V is a touring tyre for comfortable everyday driving on sealed roads. It suits drivers who want a quiet, compliant ride rather than off-road bite.
Its 103 load index carries up to 875 kg per tyre, or 3,500 kg across four. See more touring and 4x4 options from BFGoodrich.
Before you buy
- Load index. Check that 103 meets or beats your placard.
- Speed rating. V covers most SUVs and sedans in this size, but confirm against your placard.
- Use. If you tow or drive gravel often, a highway or all-terrain pattern may suit you better.
- Pairs. Replace at least both tyres on an axle so they wear and grip evenly.
- Age. Have tyres more than five years old inspected each year, even with good tread.
Need more choice?
This is a specialist size, so range is limited. Your local Bob Jane T-Marts store can check other sizes approved for your vehicle. You can also browse highway tyres for SUVs or everyday driving tyres in other sizes.
The price includes fitting, balancing, a new tubeless valve, disposal of your old tyre and GST.

Common questions
How do I find this size on my car?
Check the sidewall for 245/55R18 followed by the load and speed rating, or read the placard on the driver's door jamb.
Why does overall diameter matter?
Your speedometer, ABS and stability systems are calibrated to it. Stick to approved sizes so they keep working as designed.
Is one tyre enough choice?
If it meets your placard, yes. If not, ask your store about approved alternatives.
Can I fit 245/60R18 instead?
Only if your placard lists it. A 60-profile tyre is about 24 mm taller, which changes speedometer readings and clearance.
