BYD Sealion 7 tyres are listed in 19 and 20-inch sizes, and the choice carries a few details worth reading before you buy. Some lines pair a narrower front with a wider rear, and some are XL-rated, so the sidewall markings matter as much as the diameter.
Tyre Sizes That Fit This Collection
Below are the 19 and 20-inch sizes, shown as matching sets or front and rear pairs, with standard and XL-rated versions listed separately.
- 245/45R20 tyres: factory fitment, 2025 onwards
- 235/50R19 tyres front and 255/45R19 tyres rear: factory fitment, 2025 onwards; staggered fitment, so front and rear tyres differ
- 245/45R20 XL tyres: also listed as a fit, 2025 onwards
- 245/45R20 XL tyres front and 265/45R20 XL tyres rear: also listed as a fit, 2025 onwards; staggered fitment, so front and rear tyres differ
- 235/50R19 XL tyres front and 255/45R19 XL tyres rear: also listed as a fit, 2025 onwards; staggered fitment, so front and rear tyres differ
Read the size, load index and speed rating on your current sidewall, then compare them with the door-jamb placard. An XL tyre can stand in for a standard one only if the load index stays at or above the original. For help with the markings, visit your local Bob Jane T-Marts store.
XL tyres and the 19 or 20-inch choice
XL means extra load: the tyre is reinforced to carry more weight at a given pressure. It is a different build from a standard tyre of the same size, and it usually costs a little more.
The 20-inch 245/45R20 has a shorter sidewall than the 19-inch pair, so expect a firmer ride and more road texture. Tyres labelled for EVs, such as EV tyres, are one more option, so compare wet grip and noise ratings alongside efficiency.
Front and rear pairs
Where the front and rear sizes differ, the tyres cannot be rotated front to back. Treat each axle as its own pair, and replace both tyres on an axle together.
Keep a note of the date code on each tyre. It is a four-digit number showing the week and year of manufacture, and rubber hardens with age even when tread remains. A wheel alignment check after fitting helps the new tyres wear evenly.
The sizes above apply to the BYD Sealion 7 only. If you are also buying for another BYD, the BYD Dolphin tyres and BYD Seal tyres pages have the lists that apply to them.
FAQs
What size tyres does a BYD Sealion 7 take?
Factory sizes listed are 245/45R20, and a pair of 235/50R19 front with 255/45R19 rear. Optional XL versions exist too, so match the placard and the sidewall before ordering.
How much do BYD Sealion 7 tyres cost?
Expect to pay from $194 up to $832 per tyre, with the spread driven by wheel size and tyre type. That price includes fitting, balancing, tubeless valves, GST and removal of the old tyres.
Can I fit an XL tyre in place of a standard one?
Only when the load index meets or beats the original. Never go lower than the placard figure, and fit matching tyres across an axle so the load is shared evenly.
