My daughter has an suv with 19-inch tires. The air pump she has now doesn't stay on the larger valve stems. Does this air pump fit on the larger suv valve stems and stay on?

Hi Valerie, thanks for your question. The air pump is designed for normal-sized cars and bicycles. It is not powerful enough for SUVs, and can only inflate a little pressure slowly, so we do not suggest you use it for SUVs. You can choose other models in our store. Please contact us through Amazon message if you need any further help. Best wishes!-AstroAI
